Broadband antenna

The invention discloses a broadband antenna. The broadband antenna comprises a grounding layer, a feed microstrip line carried by the grounding layer, a radiation patch arranged on the same side of the grounding layer relative to the feed microstrip line and is separated from the feed microstrip line through an insulating dielectric layer, and a first L-shaped probe and a second L-shaped probe which are located in the insulating dielectric layer and parallel to each other; and 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, 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 the fourth arm are connected with the feed microstrip line. The broadband antenna provided by the invention has the advantages of small size, wide frequency band and high gain at the C wave band at the same time. 本发明公开了一种宽带天线，包括接地层；由接地层承载的馈电微带线；和馈电微
