Abstract
A base station antenna comprises two arrays of radiating elements each configured to emit electromagnetic radiation; two backplanes each configured to reflect respective electromagnetic radiation outwardly, wherein the two backplanes are positioned with a mechanical tilt relative to each other such that the respective electromagnetic radiation are directed in different directions in the azimuth plane; and two plate assemblies each configured to reflect a first portion of received electromagnetic radiation inwardly while allowing a second portion to pass outwardly through the respective plate assembly, where the two plate assemblies are positioned to form two Fabry-Perot cavities with the two backplanes, respectively.
