Abstract:In this article, a coplanar waveguide (CPW) fed planner monopole antenna with a compact size of 0.32λ × 0.30λ × 0.0056λ mm3 is presented. The radiator is fed with 50 Ω CPW feed line that provides impedance matching from 1.7 to 30 GHz 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 (5.04-5.40 GHz), 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. © 2018 Wiley Periodicals, Inc.
