摘要：
A dual-band dual-polarized shared-aperture antenna with suppression of cross-band scattering for base station application is presented in this article. The proposed antenna consists of a lower-frequency-band (LFB) antenna and two 1 x 3 higher-frequency-band (HFB) arrays. The LFB antenna is designed with a novel configuration. Some chokes composed of inductive and capacitive elements are introduced for scattering current suppression of the cross-band, which is the main reason for the deterioration of the radiation pattern of the HFB arrays. The measured results show that the LFB antenna with the operating frequency of 690-960 MHz and the HFB antenna with the operating frequency of 1710-2170 MHz achieve stable radiation characteristics in their respective bandwidth.
