| 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. |
