Monopole wideband antenna in uniplanar printed circuit technology, and transmission and/or recreption device incorporating such an antenna

摘要

An antenna for the transmission and/or reception of microwave signals comprises a substrate plate, at least one feeder line located on a first face of the substrate plate and a conductive deposit located on a second face of the substrate plate. The conductive deposit defines a main surface forming a ground plane for the feeder line and at least one radiating finger. The radiating finger has a first end connected to the main surface and a free end extending at least partially along one side of the main surface to form a longitudinal space between the radiating finger and the main surface. The longitudinal space forms a coupling slot for the antenna.
