Abstract
Wireless applications require compact antennas capable of operating over a wide range of frequencies with minimal power. Microstrip patch antennas are generally preferred for transceivers that operating at microwave frequencies due to their low profile and easy installation. The performance of antennas has been evaluated using the metrics collected from of return loss, Voltage Standing Wave Ratio (VSWR) and radiation pattern. The overall size of the antenna has dimensions of 34 mm × 28 mm × 1.6 mm, fabricated on FR4 substrate having relative permittivity of 4.4. The proposed antenna achieves maximum return loss of -21.30 dB at 2.9 GHz, -23.51 dB at 5.3 GHz and -19.17 dB at 10 GHz.
