Abstract

The objective of the work is to design a compact dual frequency microstrip antenna (MSA) at GSM 1800 MHz and ISM (2.4 GHz). The proposed MSA incorporates a rectangular patch with an inverted U slot printed on the top of RT duroid 5880 substrate with thickness of 0.8mm and dielectric constant of 2.2. The dimensions of the patch are optimized as 45x 54 mm2. It is fed by coaxial feeding. The parameters such as return loss (dB), gain (dB) and radiation pattern are analysed using HFSS. The prototype antenna is fabricated for the optimized dimensions and tested using vector network analyser. Simulation and measurement results are compared. Also, the performance of the antenna at dual frequencies is improved by etching double split rectangular split ring resonator at middle of ground plane.
