Abstract :
GPS, Satellite phones, requires broadband, miniature size and circularly polarized antennas. Microstrip antennas have inherently narrow bandwidth, hence demanded enhanced bandwidth and size reduction. The present paper discusses the design analysis and testing of wideband compact and circular polarized MSA. The bandwidth of designed antenna is enhanced by using EC stacked patch antenna. The designed antenna has 3 dB AR BW of 16.71% and VSWR BW (VSWR<; 2) of 20.17%. It achieves a significant amount of size reduction by loading cross slots on radiating patch. The paper also analyzes different simulated designs in terms of VSWR, AR, Impedance, Gain, Return loss. The antenna after fabrication is tested using Vector Network Analyzer (R & S 300KHz-8GHz). It was found that measured results are in good agreement with simulated results.
