Abstract

The present invention relates to an EBG (electromagnetic band gap)-based miniaturized dual band-notched UWB (ultra-wideband) antenna and belongs to the wireless communication technical field. The antenna of the invention comprises a dielectric plate, an ultra-wideband antenna, a longitudinal double-fork-shaped electromagnetic band gap structural array and a transverse double-fork-shaped electromagnetic band gap structural array, wherein the ultra-wideband antenna includes radiating units and a microstrip feeder line, is formed in a coplanar manner and is printed at the front surface of the dielectric plate, and the longitudinal double-fork-shaped electromagnetic band gap structural array and the transverse double-fork-shaped electromagnetic band gap structural array are printed at the back surface of the dielectric plate, are perpendicular to each other, and can play a role of wave trapping. The dual band-notched ultra-wideband antenna provided by the invention has the advantages of simple structure, compact size, low cost and excellent ultra-wideband and wave trapping characteristics, and can effectively suppress the interference of multi-frequency band electromagnetic signals and is suitable for compact and portable ultra-wideband terminal equipment.

Description

technical field [0001] The invention relates to an EBG-based miniaturized double-notch UWB antenna, which belongs to the technical field of wireless communication. Background technique [0002] Ultra-wideband (UWB) technology is a new type of short-distance high-speed wireless communication technology that has attracted much attention. Since the U.S. Federal Communications Commission has allocated 3.1-10.6 GHz as the UWB frequency band for civilian use, industry and academia have carried out a lot of research work in the field of UWB radio technology. As an important part of UWB system, UWB antenna has become one of the research hotspots in the antenna field. [0003] In the frequency band allocated to the existing UWB system, there are radio interference signals in multiple frequency bands, for example: WLAN signals in the 5.15-5.35 GHz and 5.725-5.825 GHz frequency bands, WiMAX signals in the 3.3-3.7 GHz and 5.725-5.85 GHz frequency bands , 7.25-7.75 GHz X-band satellite...
