Abstract

A compact MIMO antenna using a decoupling network for next generation mobile application is proposed. The proposed MIMO antenna consists of two parallel folded monopole antennas with the length of 100 mm and spacing S=6 mm and a decoupling network. In order to improve the isolation characteristic at the LTE band 13, a decoupling network was added between two antennas spaced close to each other. The decoupling network is simple and compact, which contains two transmission lines, a shunt reactive component and quarter-wavelength jointed shorting structure. The proposed MIMO antenna has the isolation of approximately 15 dB at the LTE band 13 and the ECC value less than 0.2 over the whole LTE band.
