New patch antenna for ISM band at 2.45 GHZ

In this paper we present a new patch antenna as a hexagonal patch operating in the Industrial Scientific Medical (ISM) frequency band at 2.45 GHz, the proposed antenna is verifying using to different numerical techniques which are Finite Element Method FEM and Method of Moment MoM, the compression results give us good agreement. When human body is presented near the antenna the antenna performance such as S11 and bandwidth are affected, the result demonstrates that the new antenna has negligible effect compared with that of the rectangular patch antenna.
