Abstract
This paper proposes a two element multiple-input multiple-output (MIMO) antenna with compact decoupling structure for 5G wireless communication applications. A compact decoupling structure was developed based on the elliptic curve, achieving isolation between the two antenna elements with a wideband response. The proposed concept is discussed and verified numerically and experimentally. The MIMO antenna system has demonstrated a wideband impedance matching with high isolation capability, while maintaining a good far-field and MIMO performance.
