Abstract

The invention discloses an ultra wideband antenna possessing a 6.7-7.1GHz frequency band wave trapping function. The antenna comprises a medium plate. A top surface of the medium plate is provided with a radiation paster along a center line. The radiation paster is connected to a feed microstrip line. The radiation paster is provided with two symmetrical rectangular grooves along a center line. A back side of the medium plate is provided with a corner cut land. By using the ultra wideband antenna with the wave trapping function of the invention, through the symmetrical rectangular grooves on the rectangular radiation paster, the wave trapping function is realized; through symmetrical corner cuts on a rectangular land, broadband matching is realized. The structure is simple and batch production is easy. In an actual application, working of a wideband can be realized and the wave trapping function can be performed on a signal of a C wave band 6.7-7.1GHz of Indian national satellite communication so that electromagnetic interference is avoided.

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 - WLAN (IEEE 802.11a wireless local area networks) in the 5.825GHz frequency band, Indian satellite communication C-band (IEEE INSAT / super-extended C bands) in the 6.7-7.1GHz frequency band. In 2008, Chu Qingxin of South China University of Technology used notc...
