Abstract
The utility model discloses a novel ultra-wide band antenna with groove in a shape of Chinese character shan and a symmetric resonator structure. The antenna comprises a dielectric substrate (1), a radiation unit (2), a structure groove (3) in a shape Chinese character shan on the radiation unit, a microstrip transmission line (4), metal structure resonant cavities (5), and a ground plane (6). The radiation unit, the microstrip transmission line, and the metal structure resonant cavities are printed on an upper surface of the dielectric substrate. The radiation unit is disposed in the middle part of the dielectric substrate, and trapezoid metal structure resonant cavities are disposed on two sides of the microstrip transmission line. The structure groove in the shape Chinese character shan is disposed on the radiation unit. The ultra-wide band antenna is compact in structure and small and exquisite in dimensions, and through changing dimensions and positions of the metal structure resonant cavities, notch frequency can be adjusted, so that problems of same frequency interference of an ultra-wide band communication system are solved.
