摘要：

A broadband circular polarization antenna based on the composite structure of planar spiral and longitudinal helix is presented. Compared to single spiral antenna or helix antenna, proposed antenna has a better performance at low frequency by introducing two longitudinal helix arms connecting with the terminal of the planar spiral arms. As a result, the return loss, axial ratio (AR) and gain are both improved without increasing the antenna size. The antenna is designed to operate from 2 to 18 GHz and has a physical dimension of phi 50 x 45 mm(3). A prototype was fabricated and tested, the results show that the proposed antenna can provide an AR of less than 2.5 dB, a return loss of less than -15 dB and a gain of greater than 0.5 dBi.
