Abstract
Described embodiments provide an antenna for transmitting and receiving radio frequency (RF) signals. The antenna includes an antenna element and an antenna feed network coupled to the antenna element. The antenna feed network is disposed on a first side of the antenna element. A cavity structure is disposed around the antenna feed network. The cavity structure includes conductive walls defining an antenna element cavity. The walls have a height defining a depth of the cavity. An intracavity wall is disposed within the cavity between feed lines of the antenna feed network. The intra-cavity wall is provided having dimensions selected to reduce cross-coupling within the cavity.
