ABSTRACT
There are many applications in wireless communication that involve more than one distinct band of frequencies. The
present model is a square patch array of 16x16 i.e. 256 elements arranged on the FR4 epoxy substrate material. Dual
polarization is obtained at 8 and 13 GHz frequency with return loss of -11.75dB and -18.90dB. The gain obtained from
the current model is 22dB. The present work involved the designing of array patch antenna and simulation of the
model with Ansoft HFSS. All the output parameters, radiation patterns, axial ratio and directivity are presented in
this paper.
