摘要：

A broadband and high gain circularly polarized stacked antenna with small size was designed. The antenna includes a double-Y type slot radiator and two slot-loaded patches with chamfering. Right hand circular polarization performance is achieved by adjusting the length of the two branch of Y type slot. In order to expand the antenna impedance bandwidth and axial ratio (AR) bandwidth, multilayer structure was used. Two patches with chamfering were chosen for radiating element. With the form of orthogonal, rectangular slot cut on the center of the two patches, small size of antenna can be achieved. The measurements show that, the proposed antenna's -10 dB impedance bandwidth is 32.7% (from 4.1 to 5.7 GHz), the 3 dB (AR) bandwidth is 20.7% (from 4.4 to 5.4 GHz) and the gain of the antenna is about 9 dB, which agree well with the simulations.
