Abstract
A compact three-port ultrawideband multiple-input–multiple-output (MIMO) antenna with high isolation is presented. A semi-open X-shaped slot antenna is fed by a T-shaped microstrip line to realize ultrawideband performance. Then, two L-shaped slot antennas are embedded into the designed X-shaped slot antenna to attain MIMO performance. It is worth highlighting that the loading of the L-shaped slot antennas does not increase the size of the X-shaped slot antenna, nor does it affect the antenna performance. Additionally, a decoupling scheme including two pairs of open-end slots is used to notably improve the isolations among the ports. By employing this method, a compact three-port MIMO antenna is designed. It has an ultrawide bandwidth of 115%, covering 1.70 GHz to 6.31 GHz for the reflection coefficient <−10 dB. The isolations among the ports are beyond 20 dB.
期刊介绍：
IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
