摘要: A reconfigured slot-ring antenna fed by a coplanar waveguide (CPW) is proposed for the wireless local area network dual-band applications at 2.4 and 5.2 GHz bands. The slot-ring antenna together with its feeding structure has preserved a uniplanar configuration. The slot-ring is directly connected to a feeding CPW. The slot-ring’s first and third resonant modes provide antenna’s passband. The antenna’s spurious modes are suppressed by adding to the slot-ring four metal strips at proper positions. An additional short-circuited CPW is stretched out from the end of the CPW feed, entering into the central circular patch of slot-ring to improve the impedance matching at 5.2 GHz frequency band. A pair of shunt slot tuning stubs, which are placed at the inner edge of the slot-ring, are used to tune the antenna’s third resonant frequency to 5.2 GHz. This antenna has achieved fractional bandwidths of 7.5 and 10.4% at 2.4 and 5.2 GHz frequency bands, respectively. The return losses obtained are 230.56 dB at 2.4 GHz and 241.71 dB at 5.2 GHz. Details of the antenna designs and experimental results are presented and discussed.
