Miniaturized and Multi Band Rectangular Patch Antenna Loaded with Ring Shaped Artificial Magnetic Conductor

The designing of Artificial Magnetic Conductor (AMC) backed patch antenna (PA) operating in low frequency range is state of the research. The research community is doing rigorous efforts to attain efficient antenna operating at low frequency range. In this paper, an effort has been made to design a AMC backed antenna operating at low frequency which offers dual band at 760 MHz and 940 MHz with high polarization purity of 15 dB and 21 dB and gain of 3.6 dBi and 7.1 dBi respectively. The proposed structure is best suited for the underground communication-based applications.
