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 × 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.
