Abstract

An antenna apparatus with isolated non-interactive sectors and methods operating and forming the same. In one embodiment, an antenna with a radiative element comprising a planar layer with multiple sectors is disclosed. The sectors are configured to be interactive or non-interactive. The interactive sectors contribute to the radiative profile of the antenna. The non-interactive sectors are galvanically isolated from the interactive sectors and do not substantially affect the radiative profile of the antenna. Region borders are present between various ones of the interacting and non-interacting sectors. These region borders provide the galvanic isolation between the interacting and non-interacting sectors. The antenna further includes feed portions coupled to the interactive sectors, thereby defining the antenna pattern. The non-interactive sectors are largely transparent to the radiative mode and thus do not substantially affect the antenna pattern.
