In this paper, design and implementation of multiband fractal patch antenna has been carried out. In order to make E-shaped fractal patch antenna, slots have been cut on both sides of patch to form double E-shaped fractal patch antenna. Further slots have been also cut on ground to make plus shape DGS. As result multiband fractal patch antenna with defected ground structure is obtained. By applying fractal geometry and DGS, antenna resonates at four bands 5.1 GHz, 7.8 GHz, 8.7 GHz and 9.6 GHz with good bandwidth and gain. This antenna had gain of 4.07 dBi, 4.41 dBi, 7.28 dBi and 7.33 dBi together with bandwidth of 615 MHz, 480 MHz, 640 MHz and 600 MHz at corresponding frequencies.
