Abstract

The present invention relates to a multi-stopband ultra-wideband antenna realized through split ring resonator coupling feeders, comprising a disk antenna and a split ring resonator coupling micro-strip feeder structure. The present invention is realized in a microwave dielectric substrate through printed circuit board technique. The split ring resonator coupling micro-strip feeder structure can generate stopband at a specific frequency point. A plurality of stopbands are generated by appending a plurality of split ring resonators in different sizes, so as to form a single-chip antenna feeder structure with multi-stopband characteristic. The multi-stopband ultra-wideband antenna realized through split ring resonator coupling feeders not only has ultra-wideband characteristic, but also has good inhibiting effect to interfering signals at a plurality of frequency points. The antenna is simple in structure and small in volume, meets the requirements of planar circuit integration, and has the advantages of low cost, batch production convenience, etc. Therefore, the antenna is suitable for various anti-interference ultra-wideband application occasions.

Description

technical field [0001] The invention is a multi-stop-band filter and ultra-wideband (Ultra-Wideband, UWB) antenna comprehensive design technology suitable for anti-multi-frequency signal interference. The designed antenna has an ultra-wideband antenna working bandwidth (2GHz-9.8GHz), including two parts: a disk antenna and a split ring resonator (Split Ring Resonators SRRs) coupled feeder structure. Multiple split ring resonators are coupled with the feeder to form a filter with multiple stop bands, and the filter is cascaded with the disk antenna to form an ultra-wideband antenna with three stop band characteristics. The antenna design is based on the planar printed circuit technology, using microstrip line feed, small size, suitable for high planar integration. Background technique [0002] With the rapid development of communication technology, ultra-wideband communication systems with many advantages such as low complexity, low cost, anti-multipath and anti-aliasing hav...
