Abstract
A quadrature-fed wideband CP rectangular DRA has been investigated. The Ansoft HFSS and the DWM were used in the analysis. As similar to the LP case, the fundamental TEm mode, together with the higher-order TE113 mode, of the DRA can be simultaneously excited. Since each mode can generate a CP wave, the impedance and AR bandwidth can be increased by combining the two CP modes. Both wide 10-dB impedance and 3-dB AR bandwidths of ~ 35% have been observed. Measurement results will also be presented on the conference.
