MIMO Antenna with Decoupling Network for Headset Applications

Abstract

A MIMO antenna with decoupling network for headset applications is proposed. The performance of the antenna is investigated when the antenna is placed on a head phantom. The antenna consists of two monopole type radiators and a decoupling network that improves the isolation between two radiators. The antenna on the human head phantom covers ISM band and the isolation exceeds 20 dB. Because the ECC is lower than 0.1 over the ISM band, the proposed antenna is a good candidate for diversity application.
