1. An antenna apparatus, comprising:
- a first substrate,a second substrate perpendicular to the first substrate and electrically coupled to a first edge of the first substrate,a third substrate perpendicular to the first substrate and electrically coupled with a second edge of the first substrate, the first edge and the second edge of the first substrate are opposite with respect to each other, anda fourth substrate perpendicular to the first substrate and electrically coupled to a third edge of the first substrate, wherein each of the substrates include one or more antenna elements from a plurality of antenna elements and the one or more antenna elements are selected by an antenna element selector thereby providing a particular polarization and customizable radiation pattern for the antenna apparatus to transmit or receive RF signals based on the antenna elements selected.

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.
