In this paper, a multiband Planar Inverted-F Antenna (PIFA) with high gain and appreciable bandwidth at the resonant frequencies is designed using metamaterial concept. The proposed PIFA without metamaterial is designed to resonate at 7.46GHz with return loss of -23.71dB and gain value 5.41dBi. The designed antenna is having maximum possible bandwidth of 361.8MHz. The proposed PIFA with Split Ring Resonator (SRR) loading resonates at multiple frequencies i.e. 5.60GHz, 6.68GHz, 7.98GHz, 8.44GHz and 9.42GHz. Return loss at 5.60GHz is -22.48dB and gain is 7.10dBi.
