A Novel 45 Degree Beam Steerable Antenna For Modern Communications

A novel form of Double Square Loop (DSL) antenna for beam adaptive applications is proposed. The double square loop antenna consists of two individual square loops placed at 45° to each other with a common centre. The antenna has eight feeding points on the inner track, which when excited one at a time steer the beam at 45° throughout the 360° of space. In addition, the DSL antenna operates at two different frequencies in the UWB region, thus offering a multichannel operation.
