Abstract

In this paper, elliptical slots loaded circular patch antenna for wireless communications has been investigated. The proposed antenna is modified by varying the length of ground plane to increase the impedance bandwidth over the frequency range of 1 - 10 GHz. Simulated results of proposed antenna exhibits the bandwidth of 3.34 GHz (1.46 - 4.80 GHz) and 3.01 GHz (5.05 - 8.06 GHz). The proposed antenna can be used in various wireless applications, covering the Global System for Mobile (GSM) standards (DCS 1.71 - 1.88 GHz and PCS 1.85 - 1.99 GHz), UMTS (1.92 - 2.17 GHz), Bluetooth (2.41 - 2.49 GHz) of ISM band, 2.45 GHz WLAN of IEEE 802.11 b/g/n, 5.15 GHz WLAN of IEEE 802.11 a/n, WiMAX (2.5 - 2.69 GHz, 3.4 - 3.69 GHz, and 5.25 - 5.85 GHz), X-band for satellite communication (7.25 - 8.39 GHz) and point to point high speed wireless application (5.925 - 8.5 GHz) bands. Antenna is designed and fabricated on FR4 glass epoxy substrate to validate the simulated results with the measured results. Comparisons of both the results are found to be in agreement with each other. It also shows the good omnidirectional radiation pattern, appreciable gain, and acceptable radiation efficiency over the entire frequency range of 1 - 10 GHz.
