Antenna having ultra-wideband and multiple rejection band based on bimodule and double rejection band filter

Abstract

The invention discloses a multi-stop band and ultra-wideband antenna technique based on the dual-mode and dual-stop band filters, which relates to an ultra-wideband antenna technique applicable to short distance wireless communication and data transmission. The multi-stop band and ultra-wideband antenna technique based on the dual-mode and dual-stop band filters can effectively solve the interference problems in the wideband communication system caused by the signals from the existing narrowband communication systems. The multi-stop band and ultra-wideband antenna technique based on the dual-mode and dual-stop band filters adopts the technique of dual-mode and dual-stop band filters, which realizes the technique of single-layered plane electric circuit, and is particularly suitable for the ultra-wideband communication systems in need of suppressing a plurality of interferences. The multi-stop band and ultra-wideband antenna is designed on the basis of techniques such as the dual-mode and dual-stop band filters and the disk aerials. The dual-stop band filter consists of a coupled microstrip line and a half mode substrate-integrated waveguide cavity; the coupled microstrip line and the half mode substrate-integrated waveguide cavity correspond to a resonant mode respectively so as to provide two stop bands. Realized by the general technique of single-layered PCB boards, the multi-stop band and ultra-wideband antenna based on the dual-mode and dual-stop band filters has the advantages of simple design and processing, high integration, nice suppression of the stop bands and bright application prospect in the ultra-wideband communication systems.

Description

technical field [0001] The invention relates to an ultra-wideband antenna technology applicable to short-distance wireless communication and data transmission. The antenna can effectively solve the problem that the broadband communication system is interfered by other existing narrowband communication system signals. It adopts a dual-mode dual-stop-band filter technology, which can be realized by using single-layer planar printed circuit technology, and is especially suitable for ultra-wideband communication systems that need to suppress multiple interferences. Background technique [0002] Ultra-wideband communication system has a good application prospect in short-distance wireless access and high-speed data transmission. It has made great progress in recent years, but its wide application still faces many practical problems that need to be solved. One of the important difficulties is how to deal with interference from other communication or adjacent radio frequency system...

Problems solved by technology

Compared with microstrip transmission lines, half-mode substrate integrated waveguide (HMSIW) has a higher quality factor, low loss, large power capacity, and can be well integrated with planar systems. Compared with substrate integrated waveguide ( SIW) further reduces the volume of the cavity, they can be realized by ordinary single-layer PCB technology, which is easy to process, but it is not easy to combine with microstrip to design a stop band filter
