The designs of dual band microstrip patch antennas because of their multi-functionality are becoming popular. Satellite mobile and fixed communication for Space Research, Met. Satellite, Radiolocation, Meteorological aids, aeronautical Radio navigation data and analysis has got lot of attentions in the recent years. Achieving selected multiband operation requires precise bandwidth and mutually exclusive resonating bands. Several designs with a bit modification in the basic design are proposed by placement of appropriate slots to achieve multi-band functionality in this paper. Proposed design deals with the four slot patch antenna that can control dual band operation in the range of 1.5 GHz - 2.5 GHz and 6 GHz - 10 GHz. Stable radiation patterns for the whole frequency range and for all the applications are achieved.
