Antenna assembly

Abstract

An apparatus, comprising: an antenna radiator configured to be separated from and at least partially overlapping a ground plane; and an antenna feed comprising: at least one cavity resonator configured to convey radio frequency signals, the at least one cavity resonator coupled with a filter probe configured to convey the radio frequency signals between radio circuitry and the at least one cavity resonator, and an antenna coupler configured to couple the radio frequency signals between the at least one cavity resonator and the antenna radiator, the at least one cavity resonator and the antenna coupler being configured to generate filtered radio frequency signals from the radio frequency signals received by the at least one cavity resonator and the antenna coupler.
