Pattern Matching by Optimizing Load in a Reflectarray Antenna
A novel method to match radiation pattern of a reflectarray antenna by optimizing the load is presented in this paper. By varying the load attached to each element in a reflectarray the reflection coefficient at each element is varied, which varies the overall radiation pattern of the reflectarray antenna. This paper addresses the synthesis problem, “What is the optimal loading configuration given a target radiation pattern? Mathematical solution for computing the optimal load for a target radiation pattern is presented. ADS and MATLAB simulation of a planar printed twenty-one dipoles in one dimension is included for verification.
