Abstract

A compact dual band 2 × 2 multiple-input-multiple-output (MIMO) antenna with dimension 46 × 30 × 1.6 mm3 is reported. The designed CPW-fed MIMO antenna structure consists of swastika shaped slot in the rectangular patch. A T-shaped narrow conducting strip is used in ground plane to improve the isolation between the two radiating elements. The measured lower and upper frequency bandwidths are respectively 64.96% (1.85–3.63 GHz) and 44.36% (5.07–7.96 GHz), along with the corresponding isolation \(\le -\) 17.21 dB and \(\le -\) 22.42 dB. The measured realized gain changes from 1.14 to 4.12 dBi (lower band) and from 1.42 to 4.78 dBi (upper band) and the radiation efficiency is found over 72% for both the frequency bands. The antenna diversity parameters alongwith the radiation patterns are also investigated. Initially, the antenna is modelled using CST Microwave studio and the optimized design is fabricated and measured for validity of results.
