Abstract
This article presents a compact four-element MIMO antenna for WLAN/LTE/UWB applications. The half-slot structure and half-cut monopole antenna technique are adopted to realize bandwidth from 2 GHz to 10.6 GHz while maintaining good isolation better than 15 dB and compact size of 31×31×1.6 mm. Each antenna element is composed of a quasi-semi-ellipse radiator and a protuberant ground. To be practical in a real application scenario, four antenna elements with interconnected/common ground are placed orthogonal to each other for good isolation. Key parameters affecting the antenna performance are investigated and a prototype of the proposed antenna is fabricated for measurement. The simulated and measured results agree well, testifying the proposed four-element MIMO antenna is a suitable candidate for WLAN/LTE/UWB applications.
