Abstract
The authors predict the gain performance for a CP-RLSA (circularly polarized radial line slot antenna) with reduced slot coupling and propose a basic design for slot coupling control (SCC). When the CP-RLSA can be used near the resonant frequency with weak coupling, the bandwidth becomes 1.5 times as wide as that of an antenna without SCC. SCC for this purpose is possible by the determination of the slot coupling angle. The proposed design was verified experimentally.<>
