摘要：A multi-input multi-output (MIMO) antenna with high isolation is proposed for 2.4 GHz ISM band (2.4–2.485 GHz) WBAN applications. The proposed MIMO antenna consists of two PIFA elements and utilizes an isolator composed of a shorted strip and two slits in the ground plane. Although the separation between the two PIFAs is minimized to 8 mm (0.06 ), isolation performance is improved by virtue of an isolator. To analyze the antenna’s performance on a human body, the proposed antenna is placed on a human muscle-equivalent flat phantom and is investigated through simulations. The measured −10 dB reflection coefficient bandwidth of the antenna ranges from 2.11 GHz to 2.6 GHz, and the isolation is lower than −38 dB over the 2.4 GHz ISM band.
