Summary: A wideband dual-polarized LB antenna with low cross-band scattering will be proposed for a dual-band aperture-shared array design. Its radiator consists of four slim loops with loaded periodic split-ring resonators (SRRs) for achieving low scattering property in the high-band (HB) of 3.3－4.2 GHz (24%). For this reason, the proposed LB elements become invisible to the elements operating in the HB. For proof-of-concept, a dual-wideband dual-polarized aperture-shared antenna array is designed, including the proposed low cross-band scattering LB element and 4×4 HB antenna array. Compared to the isolated HB antenna array, the variation of the HB radiation performance in the dual-band aperture-shared array is neglectable.
