摘要

在国际频谱资源有限的情况下，本文实现了一种更高效的多陷波超宽带天线窄带滤波器。本文对原设计的多缺口超宽带天线进行了改进。共面波导(CPW)耦合馈电的方式实现了宽带的加宽。该天线具有覆盖2.4GHz ~ 15.1GHz频带的大带宽，回波损耗大于10dB。在酒杯型超宽带天线的辐射贴片上采用改进的椭圆互补裂环谐振器结构，实现了陷波特征的超宽带天线。该天线在WLAN上行和下行频段均完成了带抑制，并表现出良好的滤波特性。多陷波在5.06GHz至5.46GHZ、5.72GHz至6.22GHZ频段实现。同时避免了c波段卫星通信下行频段在5.9GHz ~ 6.425 GHz的部分干扰。设计的多缺口超宽带天线在工作空间内具有良好的全向辐射性能。

Design of notch ultra-wideband antenna with new oval CRSS structure

The paper has achieved a more efficient narrow-band filter for multi-notch ultra-wideband antenna in the case of international spectrum resource constraints. The paper is improving to the original design multi-notch ultra-wideband antenna. The way of coplanar-waveguide (CPW) coupled-fed have achieved band widening. The antenna has a large bandwidth covering the frequency band from 2.4GHz∼15.1GHz with return loss larger than 10dB. There is the improved elliptical CSRR (complementary split-ring resonator) structure on the radiation patch of a wine glass shaped ultra-wideband antenna, which have achieved notch features ultra-wideband antenna. The new antenna has finished band rejection in WLAN uplink and downlink frequency bands, and exhibited excellent filtering characteristic. Multi-notch is implemented in 5.06GHz to 5.46GHZ, 5.72GHz ∼ 6.22GHZ. at the same time avoiding interference the part of the C-band satellite communications downlink frequency band in 5.9GHz ∼ 6.425 GHz. The design of multi-notch ultra-wideband antenna has a good omni-directional radiation in their workspace.
