Embodiment Construction
[0017] Below in conjunction with accompanying drawing, the present invention is described in detail as follows:
[0018] The object of the present invention is achieved in this way: the antenna mainly includes a dielectric substrate 101, a microstrip line adjacent to a coupling feed structure, an L-shaped monopole radiation unit 105, an inverted L-shaped radiation unit 1063 loaded, and a bent radiation unit 1062 and S-shaped radiating elements. The L-shaped monopole radiating unit 105, the loaded inverted L-shaped radiating unit 1063, the bent-shaped radiating unit 1062, and the S-shaped radiating unit form a series adjacent coupling feeding mechanism, and the designed adjacent coupling feeding mechanism consists of an L-shaped The microstrip transmission line and the ground plane 107 are composed. The loaded inverted L-shaped radiating unit 1063 and the bent-shaped radiating unit 1062 adopt a common feed transmission structure, and the two resonant frequencies can be adjuste...
