The design of rectangular micro strip patch antenna array with hexagonal shaped slots with DGS using inset line feeding technique has been presented in this paper. The antenna is designed and simulated by using CST software. FR-4 glass epoxy having dielectric constant 4.4 and thickness 1.6mm is used as a substrate material for the designing of proposed antenna. The different parameters of designed antenna are calculated and analyzed such as return loss, VSWR (voltage standing wave ratio), gain, radiation pattern and bandwidth. Simulation results show that the proposed antenna works on five different frequency bands. The value of return loss is -30.2 and VSWR is 1.06 at 11.2 GHz frequency bands respectively. It shows that all the values of return loss and VSWR is for X-band frequency bands are at excellent level. It shows that the results of antennas are in good agreement with results.
