## Abstract A reconfigurable design is proposed to improve the circular polarization (CP) operating bandwidth of an annular‐ring slot antenna fed with an L‐shaped coupling strip.The design involves four voltage‐controlled varactor diodes, which are placed below the slot and symmetrically distribute
