Abstract

A Multiband vivaldi antenna is designed to operate in the X and Ku bands and simulational results are presented in this paper. Along with the ultrawide band, this particular vivaldi antenna is working in the range between 7 to 20 GHz at different resonent frequencies. Gain of more than 9dB and bandwidth enhancement of 0.92% can be achieved using this model. All the antenna parameters including design considerations and field distributions are presented in this paper.

Keywords

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 16×16 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 -11.75 dB and -18.90 dB. The gain obtained from the current model is 22 dB. 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.

Keywords
