| Zusammenfassung: | The invention discloses an omnidirectional broadband antenna, which comprises a single-layer dielectric plate, a microstrip loop antenna, an H-shaped feed structure and a microstrip feed line, the microstrip loop antenna is arranged on the upper surface of the single-layer dielectric plate; the H-shaped feed structure and the microstrip feed line are arranged on the lower surface of the single-layer dielectric plate; one end of the microstrip feeder is connected with the edge of the lower surface of the single-layer dielectric plate, and the other end is connected with the H-shaped feed structure. The microstrip loop antenna is formed by arranging a rectangular notch in the middle of a rectangular metal patch attached to the upper surface of the single-layer dielectric plate, and the H-shaped feed structure rotates in the range of the rectangular notch of the microstrip loop antenna, so that the antenna has the characteristics of a groove-shaped antenna and a loop-shaped antenna at the same time, the matching |
