Abstract

The invention discloses a butterfly-shaped ultra-wideband antenna with six-notch characteristics. The butterfly-shaped ultra-wideband antenna comprises a dielectric substrate, a radiation patch, a microstrip feeder line and a rectangular grounding plate, the radiation patch is of a butterfly-shaped structure, the bottom of the radiation patch is provided with a semicircular ring connected with wings on two sides, the grounding plate is of a rectangular structure, and a rectangular groove is etched in the middle. The monopole antenna structure is adopted as the radiation patch, the ultra-wideband impedance characteristic of the antenna is achieved, the structure is novel, the notch function is generated by introducing the U-shaped and rectangular gaps, the opening resonance ring and the L-shaped branch knot, interference of narrow-band signals on an ultra-wideband communication system is effectively avoided. The ultra-wideband antenna has the advantages of novel structure, strong anti-interference capability and good radiation characteristic, and can be widely applied to various ultra-wideband communication systems.

Description

technical field [0001] The invention relates to the technical field of microwave communication, in particular to a butterfly-shaped six-notch ultra-wideband antenna. Background technique [0002] In the past few decades, the development of wireless communication technology has provided many new services, such as voice, audio, video and data services, which have changed people's daily life. In addition, it also enables faster data transmission between portable devices and computers. This high-speed data transmission can be achieved by increasing transmission power or operating bandwidth. However, many portable devices using wireless communication technology are powered by batteries, so a large bandwidth will be the solution to achieve high-speed data transmission. From this perspective, ultra-wideband communication technology will be a revolution in the field of wireless communication sexual technology. Since the U.S. Federal Communications Commission (FCC) used the 3.1-10....
