Multi-Band Rectangular Microstrip Patch Antenna with Defected Ground Structure and a Metallic Strip
Microstrip antennas and arrays are small in size any easy to manufacture. The proposed antenna is operated in the S-band and X-band with three resonant frequencies. The antenna has two resonance in the X-band used in Satellite communications Weather mapping and detecting, long-range tracking radar and missile application and the other in the S-band at 4.98 GHz frequency Wi-Fi of 13.5 Mbps with a bandwidth of 10 MHz with the QPSK modulation technique. In this paper the comparison of RMPA with and without DGS and slot is done.
