The selection of array patch antennas is mainly due to the enhancement of gain and the radiation. In the present paper we deals with the 4x4 elliptical array patch antenna designed on a special K15 nematic liquid crystal substrate material. The operating frequency is chosen at 36GHz for the desired operation and whole simulation is carried out by Ansoft HFSS. The radiation patterns, gain, filed distributions VSWR and return loss are computed and generated with the simulation results. This antenna is showing superior performance over other

traditional array\antennas as per the output parameters are concerned. The selected liquid crystal substrate K15 material is having dielectric constant of 2.88 and loss tangent of 0.01.
