摘要
In this article, a coplanar waveguide (CPW) fed planner monopole antenna with a compact size of 0.32x0.30x0.0056 mm(3) is presented. The radiator is fed with 50 CPW feed line that provides impedance matching from 1.7 to 30GHz for VSWR 2. In addition, three narrow bands are filtered out in the ultra-wideband (UWB) range. The narrow notched bands are filtered for WiMAX (3.52-4.2 GHz), WLAN (5.04-5.40GHz), and X band (8.22-9.10 GHz) application. The rejecting bands are achieved by loading a single tri-square ring resonator (SRR) on the backside of the feed line. The dimensions of SRR control the notch resonance frequencies. A single-, dual-, and tri-notch frequencies have been achieved by using single-, dual-, and tri-SRR, respectively. The measured results of antenna structures in the absence and presence of the SRR are compared with the simulations. The measured results validate the proposed design.
