Abstract

A dual-broadband printed MIMO antenna is proposed and studied. The MIMO antenna system consists of two dual-broadband antenna elements. Each element has two monopoles leading to a broadband performance. Also in order to improve the isolation, a U-shaped slot and several T-shaped little ground branch are added. The measured results show that the bandwidth(return loss >; 10dB) achieved for the dual-broadband are 2.3-3.3GHz for the lower band and 4.4 to more than 6GHz for the upper band. The isolation can reach more than 15dB in the lower band and 20dB in the upper band. The MIMO antenna has a compact volume of 60*100*0.8mm3, suitable for TD-SCDMA (2.3-2.4GHz)/LTE (2.5-2.7GHz) and WLAN 2.4(2.4-2.5GHz)/5.2(5.1-5.9GHz).
