Abstract
An antenna apparatus comprises selectable antenna elements including a plurality of dipoles and/or a plurality of slot antennas (“slot”). Each dipole and/or each slot provides gain with respect to isotropic. The dipoles may generate vertically polarized radiation and the slots may generate horizontally polarized radiation. Each antenna element may have one or more loading structures configured to decrease the footprint (i.e., the physical dimension) of the antenna element and minimize the size of the antenna apparatus.
