Book Description
Recently, there has been a rapid development of phased antenna array (PAA) systems based on low cost MMICs (monolithic microwave integrated circuits). Wideband technology has attracted considerable attention because of its high data-rate transmission capability. An investigation into novel wide band CMOS-based microwave and millimeter wave technologies has been performed in order to develop high performance phased array antenna based transmitter systems for applications including Microwave Imaging Reflectometry (MIR) systems for high temperature plasma diagnostics. This dissertation presents the design and characterization of the individual building blocks for a Ka-Band (26.5 - 40 GHz) PAA system, which includes a wideband feedback amplifier using the 0.18 [mu]m CMOS process, and a true time delay wideband Rotman lens integrated with a wideband antipodal Vivaldi antenna array on PCB. A frequency controlled feedback with parasitic cancellation technique has been employed in the amplifier design to overcome the inherent 0.18 [mu]m CMOS process limitations, thereby boosting the high-frequency response. In addition, a gain response superposition concept has been adopted to obtain a flat gain response with a compact size. This amplifier achieves a peak gain of 23.3 dB at 35.6 GHz, and maintains >16 dB gain over the entire Ka-Band. The output saturation power is 10.1 dBm. An 11-in, 9-out microstrip Rotman Lens with 30° steering angle (6° step) has been designed and implemented. A novel analytical modeling in Matlab enables fast prototyping. EM simulation has been carried out in CST afterwards. To ensure wideband operation, an antipodal Vivaldi antenna array with unbalanced microstrip line feed has been designed and integrated with the Rotman Lens. In the end, the wideband steering has been successfully demonstrated during the measurement. The analytical and experimental results of the above designs provide guidance toward the development of a new PAA system for future use in MIR systems with significantly enhanced performance.

Book Description
Multi-antenna systems are increasingly becoming more and more ubiquitous as technology improves and has proven to be advantageous in many communication applications. This dissertation addresses the challenges faced by multi-antenna systems in a variety of applications with a wide range of operating frequencies from the X-Band radio frequency (8 GHz - 12 GHz) all the way up to the W-Band (75 - 110 GHz) millimeter wave frequency regime. A novel wideband, light-weight, electronically controlled, linear 8-element phased array antenna receiver module has been demonstrated on LCP (liquid crystal polymer). Operating in the Ka-band (26.5- 40 GHz), this phased array module demonstrates the concept of a scalable phased array utilizing high density integration offered through the use of multi-layer LCP. A novel wideband planar wide slot antenna with a metamaterial inspired reactive coupling element has also been developed. Utilizing the bidirectional radiation pattern of the single antenna, a concurrent dual beam antenna array is proposed and successfully designed. This novel bidirectional array operates in the X-Band (8 - 12 GHz). In addition, state-of-the-art W-Band (75 - 110 GHz) antenna arrays for phased array applications are presented. A SIW (Substrate Integrated Waveguide) slot antenna array and a series-fed patch antenna array are designed and successfully demonstrated. Measurement techniques utilizing Zero-Bias detector beam-lead diodes are also discussed. Finally a truly scalable W-Band dual polarized, low cross polarization, phased array system is described and proposed. Antenna topology choices are discussed with respect to a scalable system level perspective. A multilayer LCP 2 x 2 tile array concept is also presented. Finally, some prototype antennas and antenna arrays are presented with simulation and measurement results.

Book Description
Recently, the ever-increasing demand for fifth-generation (5G) wireless applications has turned millimeter-wave (mm-wave) multi-beam array antenna into quite a promising research direction. Besides offering a remarkable bandwidth for high-speed wireless connectivity, the short wavelengths (1 to 10 mm) of mm-wave signals makes the size of the antenna array with beamforming network (BFN) compatible with a transceiver front-end. The high losses associated with mm-wave wireless links and systems considered the foremost challenge and may restrict the wireless communication range. Therefore, a wideband substrate integrated waveguide (SIW)-based antenna with high gain and beam scanning capabilities would be a solution for these challenges, as it can increase the coverage area of mm-wave wireless systems and mitigate the multipath interference to achieve a high signal to noise (S/N) ratio, and thereby fulfill the link budget requirements. This thesis focuses on the analysis and design of single- and multi-beam mm-wave antenna arrays based on SIW technology to fulfill the growing demand for wideband high-gain planar antenna arrays with beam steering capability at V-band. A tapered slot antenna (TSA) and cavity-backed patch antenna are used as the main radiators in these systems to achieve high-gain and high efficiency over a wide range of operating frequencies. Accordingly, numerous design challenges and BFN-related issues have been addressed in this work. Firstly, an antipodal Fermi tapered slot antenna (AFTSA) with sine-shaped corrugations is proposed at V-band. The antenna provides a flat measured gain of 20 dB with a return loss better than 22 dB. In addition, A broadband double-layer SIW-to-slotline transition is proposed to feed a planar linearly tapered slot antenna (PLTSA) covering the band 46-72 GHz. This new feeding technique, which addresses the bandwidth limits of regular microstrip-to-slotline transitions and avoids the bond wires and air bridges, is utilized to feed a 1x4 SIW-based PLTSA array. Secondly, a new cavity-backed aperture-coupled patch antenna with overlapped 1-dB gain and impedance bandwidth of 43.4 % (56-87 GHz) for |S11|
