ABSTRACT:
Several electromagnetic scattering structures are designed to improve antenna radiation patterns. The electromagnetic scattering structure has a conductive layer with certain patterns, and is applied on the radome of the base-station sector antenna. The electromagnetic waves radiating from the antenna therein induce scattering effects, which, together with the electromagnetic diffractions from the rear metal panel of the antenna, can substantially reduce the back lobe and the fields in regions not covered by the antenna. Thus, the antenna radiation patterns are improved so that a lower possibility of co-channel interferences between adjacent base stations can be achieved and therefore better efficiency of the base-station coverage also can be obtained.
