Book Description
This dissertation presents two millimeter-wave phased-antenna arrays at 28 GHz for fifth-generation (5G) mobile communication applications as well as techniques for performing in-situ self-test and self-calibration of single- and dual-polarized 5G phased-arrays. First, a scalable 64-element single-polarized transmit/receive phased array is built with 2x2 beamformer chips on a low-cost printed circuit board (PCB). The design emphasis is placed on minimizing the printed circuit board cost, optimizing the cross-polarization performance, and on-grid scalability. The array is capable of scanning +/-50 deg. in azimuth and +/-45deg. in elevation at 29 GHz with cross-polarization rejection better than 20 dB. It achieves an effective isotropic radiated power (EIRP) >50 dBm over a 4 GHz bandwidth from 27 to 31 GHz. Therefore, it is a suitable candidate for Gbps multi-user multiple-input multiple-output (MU-MIMO) base-station applications. Second, a 2x64-element dual-polarized dual-beam phased array for 5G polarization MIMO is built. The phased-array has two 1:16 dual Wilkinson networks and microstrip antennas with rotated feeds for cross-polarization cancellation. The array demonstrates a measured effective isotropic radiated power (EIRP) at Psat of 52 dBm for each beam and is capable of scanning +/-50 deg.in azimuth and +/-25 deg. in elevation with >28-dB cross-polarization rejection. Simultaneous dual-beam operation is demonstrated with near-ideal patterns for each beam. The array demonstrates independent simultaneously transmitted 2x16-quadrature amplitude modulation (QAM) and 2x64- QAM data streams delivering an aggregate maximum data rate of 2x20 and 2x30 Gb/s, respectively. Next, the problem of phased-array calibration is considered. Two calibration techniques are developed and tested for calibrating single and dual-polarized 5G phased arrays at 28 GHz.The first technique addresses the calibration of single-polarized phased-arrays in a MU-MIMO hybrid beamforming base station system. The procedure, labeled Quad-BIST, enables built-in self-test (BIST) and self-calibration of the arrays in-situ without having to remove the array from the field. Quad-BIST relies on mutual coupling between antennas in neighboring arrays arranged in Quad-fashion to extract the calibration coefficients and perform channel characterization. Quad-BIST was successfully applied to 5G 28 GHz arrays with 4x4 and 8x8 elements in each quadrant. The results show that Quad-BIST predicts the channel states (gain and phase control) with rms errors of 0.2 dB/2 deg. and 0.4 dB/2.5 deg. for the 4x4 and 8x8 quadrants, respectively, as compared to far-field techniques. The relative channel ratios are found to be within rms errors of0.8 dB/7.5deg.. Near-ideal patterns are attained using the quadrant-level calibration for both arrays with side-lobe level's below -20 dB over scan. The second technique is for the calibration of dual-polarized dual-beam phased arrays. The procedure, labeled (DP-BIST), exploits the mutual coupling between different antennas of orthogonally polarized beams sharing the same aperture to enable in-situ self-calibration and self-test of the phased array channels of each beam. DP-BIST was applied to a 16-element dual-polarized dual-beam linear phased-array at 29 GHz, and predicted the relative channel states (gain and phase control) with rms errors better than 0.3 dB /3 deg. and the relative channel offsets with rms errors of 0.8 dB /6 deg. over a wide-bandwidth. These results demonstrate its feasibility for use in 5G polarization MIMO phased arrays.

Book Description
This book presents state-of-the-art millimetre wave antennas for next generation 5G communications. The propagation losses associated with the millimetre waves and the signal blockage due to the objects present between transmitter and receiver require novel antenna topologies to address these issues. Various aspects of antenna design related to millimetre wave 5G communication including 28-GHz channel characteristics, mmWave antenna requirements, antenna design strategies for 28 GHz, MIMO/multibeam antennas, and mmWave lens antennas are highlighted. Apart from the general antenna requirements and study related to the 28 GHz frequency band, various new metamaterial-based antennas employing uniaxial or biaxial anisotropic media that enhance the antenna radiation performance are covered in detail. In addition, various new antenna systems such as wide-scan antenna arrays, dual-polarized antennas, and dual-beam/multibeam antennas are covered in this book. The book concludes with the glimpses of the millimetre wave lens antennas and the design of very thin planar metamaterial lens for 5G massive MIMO applications.

Book Description
The evolution of the wireless communication systems to the future generation is accompanied by a huge improvement in the system performance through providing a high data rate with low latency. These systems require access to millimeter wave (mmWave) bands, which offer several advantages such as physically smaller components and much wider bandwidthcomparedtomicrowavefrequencies. However, mmWavecomponentsstillneed a significant improvement to follow the rapid variations in future technologies. Although mmWave frequencies can carry more data, they are limited in terms of their penetration capabilities and their coverage range. Moreover, these frequencies avoid deploying traditional guiding technologies such as microstrip lines due to high radiation and material losses. Hence, utilizing new guiding structure techniques such as Printed Ridge Gap Waveguide (PRGW) is essential in future mmWave systems implementation. ThemainpurposeofthisthesisistodesignmmWavecomponents,antennasubsystems and utilize both in beam switching systems. The major mmWave components addressed in this thesis are hybrid coupler, crossover, and differential power divider where the host guidingstructureisthePRGW.Inaddition,variousdesignsfordifferentialfeedingPRGW antennas and antenna arrays are presented featuring wide bandwidth and high gain in mmWave band. Moreover, the integration of both the proposed components and the featured antennas is introduced. This can be considered as a significant step toward the requirements fulfillment of today's advanced communication systems enabling both space and polarization diversity. The proposed components are designed to meet the future ever-increasing consumer experience and technical requirements such as low loss, compact size, and low-cost fabrication. This directed the presented research to have a contribution into three major parts. The first part highlights the feeding structures, where mmWave PRGW directional couplers and differential feeding power divider are designed and validated. These components are among the most important passive elements of microwave circuits used in antennabeam-switchingnetworks. Different3-dBquadraturehybridcouplersandcrossover prototypes are proposed, featured with a compact size and a wide bandwidth beyond 10 % at 30 GHz. In the second part, a beam switching network implemented using hybrid couplers is presented. The proposed beam switching network is a 4 × 4 PRGW Butler matrix that used to feed a Magneto-electric (ME) dipole antenna array. As a result, a 2-D scanning antenna array with a compact size, wide bandwidth, and high radiation efficiency larger than84%isachieved. Furthergainenhancementof5dBiisachievedthroughdeployinga hybridgainenhancementtechniqueincludingAMCmushroomshapesaroundtheantenna array with a dielectric superstrate located in the broadside direction. The proposed scanning antenna array can be considered as a step toward the desired improvement in the data rate and coverage through enabling the space diversity for the communication link. The final activity is related to the development of high-gain wide-band mmWave antenna arrays for potential use in future mmWave applications. The first proposed configuration is a differential feeding circular polarized aperture antenna array implemented with PRGW technology. Differential feeding antenna designs offer more advantages than single- ended antennas for mmWave communications as they are easy to be integrated with differential mmWave monolithic ICs that have high common-mode rejection ratio providing an immunity of the environmental noise. The proposed differential feeding antenna array is designed and fabricated, which featured with a stable high gain and a high radiation efficiency over a wide bandwidth. Another proposed configuration is a dualpolarized ME-dipole PRGW antenna array for mmWave wireless communication. Dual polarizationisconsideredoneofthemostimportantantennasolutionsthatcansavecosts and space for modern communication systems. In addition, it is an effective strategy for multiple-input and multiple-output systems that can reduce the size of multiple antennas systems by utilizing extra orthogonal polarization. The proposed dual- polarized antenna array is designed to achieve a stable gain of 15 ± 1 dBi with low cross- polarization less than -30 dB over a wide frequency range of 20 % at 30 GHz.

Book Description
Demands of multi-standard operation have risen in millimeter-wave 5G phased arrays, in order to achieve more band coverage, reduce fabrication and deployment costs and realize inter-band carrier aggregation. This dissertation investigates dual-band and wideband design approaches to realize multi-standard phased array systems. In the dual-band approach, a 32-element dual-band, dual-beam phased array is designed by integrating dual-band patch antennas with commercial narrowband beamformers. Another design introduces an 8-element dual-band, dual-polarized, dual-beam phased array targeted at compact system applications. Both designs achieve 26-29 GHz and 37-41 GHz operation. In the wideband phased array approach, a novel stacked wideband dipole antenna is developed and integrated with a wideband SiGe Tx/Rx beamformers to achieve operation of 23-46 GHz. A single-polarized 64-element array and a dual-polarized 8-element array are then demonstrated with state-of-the-art performance. The 64-element array achieves a maximum EIRP of 50 dBm at P1dB operation, and 8-element dual-pol. array achieves 29 dBm. Both arrays demonstrate less than 4% EVM when transmitting 64-QAM 5G OFDM signal with 6-8 dB backoff from P1dB.
