A CPW Loaded Quasi-T Shaped Planar Antenna for WLAN and X-Band Applications

In this paper, a compact, geometrically simple, dual band and high gain coplanar waveguide (CPW) fed antenna for WLAN and X-band is proposed. The antenna is designed on Rogers RT/Duroid 5880 substrate with overall size of 25 mm × 33 mm × 0.79 mm. The proposed antenna consists of circular and rectangular stubs with one rectangular slot. The stubs and slots are introduced in order to achieve the desired bandwidth and high gain. The proposed antenna is designed and analyzed using the electromagnetic (EM) tool HFSS. Moreover, the proposed antenna design is compared to previously published work, and the comparison shows that our proposed antenna is a good candidate for radar applications.
