Abstract

The invention discloses an ultra-broadband antenna with a trapping function in the 6.7-7.1GHz frequency band, which includes a dielectric plate, a radiation patch is arranged on the top surface of the dielectric plate along the center line, and the radiation patch is connected with a feeder microstrip line. There are two symmetrical rectangular grooves along the center line in the radiation patch; a chamfered ground is provided on the back of the dielectric board. The ultra-broadband antenna with notch function of the present invention realizes the notch function through symmetrical rectangular slots on the rectangular radiation patch, realizes broadband matching through symmetrical cut corners on the rectangular ground, has a simple structure, and is easy to produce in batches. In practical applications Not only can realize the work of broadband, but also can realize the function of trapping the signal of Indian National Satellite Communication C-band 6.7‑7.1GHz to avoid electromagnetic interference.

Description

technical field [0001] The invention belongs to the technical field of ultra-wideband antennas, and relates to an ultra-wideband antenna with a notch function in the 6.7-7.1GHz frequency band. Background technique [0002] As an important part of UWB systems, UWB antennas have been widely studied due to their small size, low processing cost, easy processing, and easy integration with associated circuits. [0003] However, there will be some other communication frequency bands in the entire ultra-wideband operating frequency band 3.1-10.6GHz that will interfere with ultra-wideband communication, such as WiMAX (IEEE802.16 Worldwide Interoperability for Microwave Access) operating in the 3.4-3.69GHz frequency band, 5.15- 5.825GHz frequency band WLAN (IEEE 802.11awireless local area networks), 6.7-7.1GHz Indian satellite communication C band (IEEE INSAT / super-extended C bands). In 2008, Chu Qingxin of South China University of Technology used notched annular grooves on the micr...
