GSM, GPS and WI-FI Loop Type Ground Radiation Mobile Antenna

Abstract

A loop type ground radiation antenna has been analyzed using an equivalent circuit model in this study. The circuit model has been selected in such a way that the design parameters of the ground radiation antenna can be mapped onto the circuit. Ever increasing development in mobile devices has emphasized the importance of embedded electrically small antennas. Therefore, the current design approach of the antenna is based on the past experience of design engineers so to demonstrate the accuracy of the proposed model, a typical loop type ground radiation antenna with rectangular ground clearance is designed in HFSS at 2.45 GHz for Wi-Fi, at 1.57 GHz for GPS and 0.9 GHz for GSM.
