Broadband antenna

The utility model discloses a broadband antenna. The broadband antenna comprises a grounding layer, a feed microstrip line carried by the ground layer; the radiation patch and the feed microstrip lineare arranged on the same side of the grounding layer, and the radiation patch and the feed microstrip line are separated through an insulating dielectric layer; wherein the first L-shaped probe and the second L-shaped probe are located in the insulating medium layer and are parallel to each other, the first L-shaped probe is composed of a first arm and a second arm, the second L-shaped probe is composed of a third arm and a fourth arm, and the first arm and the third arm are arranged below the radiation patch and are parallel to the radiation patch. And the open ends of the second arm and thefourth arm are connected with a feed microstrip line. The broadband antenna provided by the utility model has the advantages of small size, wide frequency band and high gain at the same time at the Cwave band. 本实用新型公开了一种宽带天线，
