Abstract

This paper presents a differential fed monopole antenna with Multi Input Multi Output (MIMO) configuration. Two models are proposed for wide band communication systems with defected ground structure on the other side of the substrate. The basic model and the proposed modified model are showing excellent radiation characteristics in the wide operating band. The simulation results are carried with commercial electromagnetic tool HFSS and the antenna parameters are analyzed a presented in this work. The proposed antenna is prototyped on FR4 substrate with dielectric constant 4.4 and the measured results on network analyser are compared with simulation results for validation. The polarization purity when compared with base model; the proposed model is showing better results especially at high frequency bands.
