This research article contains process of RMPA modification into triple band feeler using negative media or metamaterial. The metamaterial structure contains amalgamation of rectangular and circular shapes to form a design which improvise the patch results to a great extent. The centre of interest in this letter is to use a microstrip patch antenna to operate at three different frequencies instead at operating frequency alone. This triple band feeler can operate at three distinguished frequencies 1.941, 2.586 & 2.784 GHz. whereas the operating frequency was 2GHz. The return loss for all the band frequencies is -29.1, -27.3 and -22.4 dB respectively and corresponding bandwidths are 23.7, 35.2 and 27MHz compared with return loss -10.11dB and bandwidth 9.4MHZ achieved by RMPA alone. All the designing and simulation work was done in the CST-MWS and the proving that the negative media is metamaterial was accomplished by MS excel software.
