Rao-Wilton-Glisson (RWG) edge elements are widely used to determine the performance of an antenna specially the distribution of elemental dipole on the antenna surface, surface current distribution, profile of input impedance and radiation pattern. In this paper the impact of geometry and position of feed point of a patch antenna is analyzed in terms of variation of input impedance against frequency to get the bandwidth of the antenna and radiation pattern on both two dimensional surface and three dimensional space. Finally an array of such antenna is placed on a line to observe the end fire and broad side radiation pattern to get intense and heavily directed beam, can be used as substitute of multi hop ad-hoc link.
