Interference Rejection Capability of Cross Dipole Antenna Array System

Abstract

A suitable use of the antenna array in the wireless communication system can result in improvement in the signal to interference ratio (SIR). SIR is in general function of antenna type, and the number of the antenna elements, angle of arrival and the polarization of the desired source. In this paper we take into consideration uniform linear array of dipole and cross dipole antenna and study the effect of different polarization and varying the number of elements on the SIR. A comparison between uniform linear array of dipole and cross dipole antenna shows that cross dipole antenna have better performance in terms of SIR and is more optimize in term of elements
