✦ Synopsis

Abstract

A compact MIMO antenna using a decoupling network for 4G USB dongle application is proposed. The proposed MIMO antenna consists of two parallel folded monopole antennas with the length of 100 mm and a decoupling network. To improve the isolation characteristic at the LTE band 13, a decoupling network was added between the two antennas placed close to each other. The decoupling network is simple and compact and consists of two sections of transmission line, a shunt reactive component and quarter‐wavelength jointed shorting structure. The proposed MIMO antenna has the isolation less than −15 dB at the LTE band 13 and the ECC is lower than 0.4 over the whole LTE band. © 2010 Wiley Periodicals, Inc.
