Abstract

The invention provides a tooth-shaped miniature ultra-wideband antenna with loaded star-shaped gaps. The antenna belongs to the field of wireless communication technology. The tooth-shaped miniature ultra-wideband antenna with the loaded star-shaped gaps is composed of a dielectric board (1), a radiating unit (2), an impedance converter (6), a 50-ohm feed line (7), a grounding unit (8), and an F-shaped paster (9), wherein the radiating unit (2), the impedance converter (6), the 50-ohm feed line are printed on the front side of the dielectric board (1), the grounding unit (8) and the F-shaped paster (9) are printed on the back surface of the dielectric board. The tooth-shaped miniature ultra-wideband antenna is characterized in that one large hexagram gap (3) and six small hexagram gaps (4)are loaded on the radiating unit (2), and furthermore 24 semi-hexagram pasters (5) are expanded from the edge of the radiating unit; and b, the grounding unit (8) is connected with the F-shaped structure paster (9). The tooth-shaped miniature ultra-wideband antenna has advantages of 1, ultra-wideband; 2, compact structure and small size; and 3, low manufacturing cost.

Description

technical field [0001] The invention relates to a tooth-shaped miniaturized ultra-wideband antenna loaded with star-shaped slots, and belongs to the technical field of wireless communication. Background technique [0002] Microstrip antennas are the most basic and commonly used antennas, and their main forms are microstrip patch antennas, microstrip dipole antennas, microstrip line antennas and microstrip slot antennas. Compared with ordinary microwave antennas, microstrip antennas have the advantages of low profile, easy integration, and easy access to circular polarization and multiple frequency bands, and have been widely used. However, the conventional design of the microstrip antenna has a narrow frequency band and low power capacity. At the same time, the conductor and dielectric loss are large, which reduces the radiation efficiency. [0003] However, with the development of the wireless communication field, the requirements for microwave devices such as low loss, ul...
