電気的に制御可能なスプリットリングスロットを装荷した円偏波切り替えマイクロストリップアンテナの設計と解析

抄録

This paper proposes a simple circular-polarization (CP) switchable microstrip patch antenna design. Reported CP-switchable antennas require a large number of diodes and choke components. Therefore, the proposed antenna aims to streamline these design components using a patch loaded with an electrically activated split-ring slot and a center via hole. This configuration allows the antenna to advance for switching operation while maintaining the patch compact. The impact of the split-ring slot is analyzed and presented in detail for the target CP characteristics.
