A High Isolation UWB MIMO Antenna based on Angle Diversity

摘要

A UWB MIMO antenna based on angle diversity technology is proposed in this paper. This antenna integrates Vivaldi antenna and UWB slot antenna with a compact size of 26×26mm^{2, the difference of radiation pattern can realize lower coupling between different antenna units. Less than −19 dB isolation between different ports can be obtained through the whole UWB band (3.1-10.6GHz). In addition, the combination of one C-Shaped structure and two L-Shaped structures (CLL) avoids the interference of WLAN (5.125-5.825GHz) band. The proposed antenna has good performance, which is suitable for UWB communication system.}
