Abstract

In this paper, a stacked patch multiband, CPW (coplanar waveguide) fed, slotted ground micro strip patch antenna is designed for wireless application. The proposed antenna consists of an upper patch, stacked over a lower radiating patch, along with a CPW feed above slotted ground plane. The wideband radiation of the antenna is achieved using a CPW feed in the lower patch and a stacked square patch along with slotted ground plane. The proposed antenna operates into four different bands. The measured 10dB return loss bandwidth of proposed antenna is 7.25%(3.3-3.55Ghz), 10.03%(4.1-4.524Ghz), 2.62%(4.91-5.03Ghz) and 6.6%(5.71-6.1Ghz) at center frequency 3.458 GHz, 4.188 GHz, 4.954 GHz, 5.893 GHz, with gain of 2.67dB, 4.79dB, 3.07dB, and 3.62dB. The proposed antenna is applicable for Wi-Max, WLAN and Radar Altimeter and satellite application. The proposed antenna is designed on a Multilayer FR4 dielectric with permittivity 4.6, loss tangent 0.001 and thickness 1.588mm. Antenna is designed and simulated using Advanced Design System (ADS) 2011.05 software.
