Abstract
A multi-input multi-output (MIMO) antenna with high isolation is proposed for 2.4GHz 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 lambda(o)), 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.
