Abstract: Today’s communication demand the antennas those are capable to handle the two (or) more frequencies. Here a single patch of srichakra shape microstrip radiator is proposed. Design can be made up of the Rogers RO 3003 material of thickness 1 mm. The antenna is made by cutting the Hexagram slots in a circular patch. This can be modelled by the commercial software HFSS. From the achieved results the antenna operated in NATO J-band, Ka-band and K-bands with the gains 5.368dB, 8.13dB, 8.52dB, 8.89dB at the centre frequencies 12.2GHz, 23GHz, 25.8GHz, and 31.8GHz respectively. 
Keyword: Srichakra, Hexagram Slot, NATO J-band, Ka-Band, K-band.
