Ultra-wideband antenna based on double T-shaped slot

The utility model relates to an ultra-wideband antenna based on double T-shaped slots. The ultra-wideband antenna comprises a grounding metal plate (1), a dielectric substrate (2), a 50 Ohm microstrip feeder (3), an impedance transformer (4), a radiation patch (5) and two T-shaped slots (61, 62), wherein the 50 Ohm microstrip feeder (3), the impedance transformer (4) and the radiation patch (5) are arranged on the upper surface of the dielectric substrate (2), the grounding metal plate (1) is arranged on the lower surface of the dielectric substrate (2), and the two T-shaped slots (6) can adjust impedance matching and expand the bandwidth. The ultra-wideband antenna based on the double T-shaped slots can completely cover a range from 3.1 to 10.6GHz, has the advantages of simple structure, compact configuration, low manufacturing cost and the like, and is expected to play an important role in the technical field of ultra-wideband antennas.
