Abstract

In this letter, the Multiple input multiple output (MIMO) slot antenna with a compact structure is presented. The decoupling method is based on the orthogonal modes of the antenna, thereby making it unneccesary to have additional decoupling branches. With experimental results, the authors demonstrate that an aperture-shared slot antenna loading a capacitor with a 0402 package can achieve isolation enhancement of 9 dB, an envelope correlation coefficient (ECC) of lower than 0.2 between ports, and a wide -3 dB efficiency bandwidth across the desired bands. Dual-band 4×4 MIMO antennas are designed and integrated into an ultra-thin blade-type router; simulated results indicate that the proposed design has great potential for WiFi 6/6E applications.
