Abstract

The present invention relates to a multi-stopband ultra-wideband antenna realized through patch gap etching, which consists of a dielectric substrate (1) and a metal clad layer(2) on the dielectric substrate (1). A feeder line part adopts a coplanar waveguide form, and consists of a signal line (3), gaps (4) and metal areas (5) which are symmetrically distributed on two sides of the signal line (3); a radiation unit (6) adopts a disk form; an extended end of the signal line (3), which is slightly longer than the metal areas (5) on two sides, is connected with the radiation unit (6); the antenna has ultra-wideband characteristic, which can meet the requirements of ultra-wideband communication systems; meanwhile, the antenna can generate stopbands at three frequencies, thereby having the performance of resisting multiple frequency point interference. As the frequency of the antenna stopband can be freely regulated by changing etching gap length, the antenna has stopband adjustability, which can satisfy the application in some special interference frequency occasions. In addition, the increase of etching gaps can realize more stopband characteristics.

Description

technical field [0001] The invention is an ultra-wideband (Ultra-Wideband, UWB) antenna design technology suitable for anti-multi-frequency signal interference. It belongs to the technical field of antenna design. Background technique [0002] Ultra-wideband communication system has many advantages such as low complexity, low cost, anti-multipath and anti-aliasing, etc. It is suitable for the development of high-speed communication and has been widely used. In recent years, as an important part of UWB systems, UWB antennas have also received more attention, and the corresponding design requirements have also become higher and higher. At present, in the microwave frequency band, there are a large number of services in the lower frequency band and it is very crowded. Since the ultra-wideband communication system occupies a very wide frequency band (for example, the UWB frequency band recognized by the US FCC is 3.1GHz-10.6GHz), there are inevitably Problems with interfering ...
