The stack antenna technique used to improve the antenna characteristics of the printed patch antenna structures. The method of stacking varies for each material. In this work we used graphene as the radiating material. The improvement in the parameters is achieved by edge truncation and ground plane optimization techniques. The main factor to affect the stacking is the curing temperature and the heat absorbing nature of the substrate and air gap between layers. In this work we have experimented and analysed the effect of multilayer stacking on printed antenna structures and its effect on the antenna performance. The antenna is designed for 2.45 GHz ISM Band applications and the gain is more than + 5 dB. In this paper we tried to replace the copper with multilayer graphene based printed structure.
