Abstract
Reflector antenna configurations have evolved considerably in the last decade. For example, a reflector antenna configuration envisioned for future satellite communications is shown in Fig. 1. This antenna system utilizes a dual offet reflector antenna with the following characteristics: (a) the main reflector is mesh deployable, (b) the subreflector is made of multi-layered frequency selective surfaces (FSS), (c) a deployable mast is shown to support the subreflector, (d) there are complex conformai array feeds operating at different frequency bands, and (e) adaptive beam forming networks (BFN) with reconfigurable functionality are used. This antenna system architecture is envisioned to fulfill the demanding requirements imposed upon the future - generation antenna systems. Some of the key design aspects of these future-generation antenna systems are high gain, low sidelobes, low cross polarization, multi-frequency operation and scanning beam capabilities. Clearly, sophisticated and advanced analytical/numerical and measurement techniques are required to accurately and properly assess the performance characteristics of this type of an antenna configuration.
