Abstract
In this article, a novel geometry for the multiple input multiple output (MIMO) array slot antenna with directive radiation patterns for WLAN (IEEE 802.11ac) & ITU applications is proposed. By using a two sub-element topology, a combined novel element is obtained. The proposed MIMO array slot antenna illustrates beneficences in terms of small size with physical dimensions of 8.5λh×8.5λh and relatively high front-to-back ratio without using reflectors and directors with approximately 20dB F/B. Therefore, a compact MIMO antenna array with high isolation among those the combined elements are obtained. The practicality of the proposed MIMO is validated by Simulated and measured results.
