Design and Physical Realization of Phased Array Antennas for MIMO/Beam Steering Applications 10 www.cadence.com/go/awr Generating Designs from the Wizard One goal of the phased array generator wizard is to provide designers with a powerful yet intuitive interface to define a physi- cal-array configuration, assign antenna and RF link characteristics to individual and/or groups of elements, define feed networks and gain taper properties, and simulate the response, inclusive of potential element failure. This enables users to produce a far-field plot that can be swept for frequency, input power, and phi and theta angles using slide tuners to control these parameter values. The resulting antenna pattern view provides designers with a real-time visual aid depicting the impact of design decisions on far-field performance. Developing actual phased array hardware requires the design and simulation focus to shift toward circuit-level analysis and physically realizable components. The entire available design flow, from antenna synthesis, generation of antenna radiation patterns through EM analysis, configuration of the array and feed network, and generation of circuit- or system-based schematic design is shown in Figure 10. AWR software addresses additional design detail and in-depth analysis to support further hardware development, including full EM simulation of the entire array along with co-simulation of the feed structure represented by circuit- and system-level behavioral blocks constructed from information defined by the user in the phased array generator wizard.
