Resonant cavity antennas (RCAs) are usually used in applications that require high-gain antennas. High-gain is achieved by using highly-reflective frequency selective surfaces (FSSs) as the superstrate and adjusting the height of the RCA [1]. In this paper, different types of FSSs are employed as RCA superstrates. The formulation provided in [1] implies that the RCA directivity only depends on the reflection coefficient magnitude of the FSS superstrate. In this paper, it is shown that the… CONTINUE READING
