摘要：

A new technique is presented to realize dual-linear polarization in four-arm sinuous antennas by simultaneously exciting all four arms of the antenna with a non-sequentially phased input. A hollow metallic cavity backing is used to obtain uni-directional radiation. The antenna exhibits a low input reflection coefficient in multiple bands across a frequency range from 1 to 4 GHz. A high level of cross-polarization rejection throughout the bandwidth of operation is demonstrated. Measurements show good agreement wtih electromagnetic simulation results.
