This work proposed an UWB filter with a notch band located at 5–6 GHz fabricated on a 0.8-mm thick FR4 substrate, which can reject the 5.2/5.8 GHz WLAN and 5.5 GHz WiMAX signals and suppress the coexistent interference in the UWB spectrum, is presented. Fig. 1 shows the prototype of the proposed filter design, where the filter is basically implemented using a co-planar waveguide (CPW) structure on a single substrate. In this filter design, a bandpass filter with the passband being 3.1–10.6 GHz is first designed by a CPW with four short-circuited stubs using the standard filter design formulas and based on genetic-algorithm (GA) is then applied to simultaneously search for the appropriate circuit topology and the corresponding electrical parameters with UWB characteristic. Then the split ring resonators (SRRs) etched on the center strip of the CPW or the complementary split ring resonator (CSRRs) deposited on the backside of the substrate are employed in the filter to create the desired band-notched characteristics. The SRR and CSRR, which has been fully studied in [1], can excite resonant modes and thus the band-stop features at a desired frequency band with suitable designs.

    這工作提出了與山谷帶的UWB過濾器被製造的5-6 GHz位于0.8mm厚實的FR4基體,可能拒绝5.2/5.8 GHz WLAN和5.5 GHz WiMAX信號並且壓制在UWB光譜的共存干涉,被提出。 图1顯示提出的過濾器設計的原型,使用在一個唯一基體的一個共面波導(CPW)結構過濾器基本上被實施。 在這個過濾器設計,與是的通頻帶的一臺带通滤波器3.1-10.6 GHz由與四個短路的殘餘部分的CPW首先設計使用標準過濾器設計慣例,並且基于基因算法(GA)然後被申請於同時搜尋適當的電路拓撲結構和與UWB特徵的對應的電子參量。 然后在基體的後側方或補全分裂圓環諧振器(CSRRs)的放置的中心小條(SRRs)銘刻的分裂圓環諧振器CPW在過濾器被使用創造期望帶被刻凹痕的特徵。 SRR和CSRR,充分地被學習了[1],可能激發共振方式和因而band-stop特點在與適當的設計的一個期望频带。
