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.
