摘要:
分析了采用贴片式频率选择表面(FSS)为盖板、U形缝隙矩形贴片为辐射器的Fabry-Perot谐振器印刷天线,揭示了其天线频带远窄于辐射器频带的原因.鉴于上述Fabry-Perot谐振器天线的实用频带主要受限于谐振型的盖板,因此要展宽实用频带,就应弱化盖板的谐振特性,所以提出将FSS中相同尺寸的方形贴片改进成沿一维或二维渐变尺寸的结构.同时应增宽阻抗频带和增益频带及其相互交叠的带域,即增宽可利用的公共频带.仿真结果显示这种改进增宽了此类天线兼顾高定向性和阻抗匹配的实用频带.
Abstract:
A printed Fabry-Perot(F-P)resonator antenna, consisting of frequency selective surface(FSS)with patch elements as the cover and U-slotted patch as the radiator, is analyzed. The reason why the bandwidth of this antenna is obviously narrower than that of the radiator is discovered. The practical bandwidth of above Fabry-Perot resonator antenna is restricted by the resonant cover. To broaden the practical bandwidth, the resonant character of the cover should be weakened, so a scheme is proposed to replace the uniform patches by 1-D or 2-D tapered-sized patches. At the same time, both the impedance bandwidth and gain bandwidth should be broadened and overlapped each other as possible, i.e. extend their available common bandwidth. Simulation results show that this antenna can broaden the practical bandwidth for both higher directivity and impedance matching.
