Abstract

In this paper, a tri-band H-shaped microstrip patch antenna is presented for DCS and WLAN (IEEE 802.11a/b/g) applications. The proposed antenna has symmetrical properties and has been designed by etching H-shape structure on FR-4 substrate with coaxially fed input. It radiates for DCS (1.79-1.81 GHz) and WLAN (2.43-2.47 GHz, 5.11-5.27 GHz) frequency bands. It is demonstrated that the fabricated antenna offers improved values of S₁₁ and VSWR. The noted gain at 1.8 GHz, 2.45 GHz and 5.2 GHz are 1.6 dBi, 1.9 dBi and 2.1 dBi, respectively. The return loss S₁₁ of the fabricated antenna was simulated using Ansoft HFSS which was in good agreement with experimental data.
