This antenna is designed to operate in 2 frequencies that range from 1.610-1.625 GHz and 2.483-2.5 GHz. The design is obtained by using a single Microstrip patch antenna with a single feed by inserting two pair of slits placed near the edges of the patch. An air gap has been inserted to improve the gain. The proposed design provides dual band operation in L and S band as well Circular Polarization needed for the hand held receivers of IRNSS & GPS systems. The work is done using Ansoft HFSS software and the designed antenna can be used in other wireless applications to have multi-band operation and to have compact structure.
