Abstract

A system and method for a wireless link to a remote receiver includes a communication device for generating RF and an antenna apparatus for transmitting the RF. The antenna apparatus comprises a plurality of substantially coplanar modified dipoles. Each modified dipole provides gain with respect to isotropic and a horizontally polarized directional radiation pattern. Further, each modified dipole has one or more loading structures configured to decrease the footprint (i.e., the physical dimension) of the modified dipole and minimize the size of the antenna apparatus. The modified dipoles may be electrically switched to result in various radiation patterns. With multiple of the plurality of modified dipoles active, the antenna apparatus may form an omnidirectional horizontally polarized radiation pattern. One or more directors may be included to concentrate the radiation pattern. The antenna apparatus may be conformally mounted to a housing containing the communication device and the antenna apparatus.
