Planar MIMO Antenna with Slits for WBAN Applications

الملخص EN

A planar MIMO antenna with slits for WBAN applications is proposed.

The antenna consists of two PIFAs, ground pads, and two slits.

By adding ground pads, the antenna size is reduced with improved impedance matching.

Through two slits in a ground plane, the isolation characteristic is improved and the resonant frequency can be controlled.

To analyze the antenna performance on a human body, the proposed antenna on a human equivalent flat phantom is investigated through simulations.

Regardless of the existence of the phantom, the antenna operates in 2.4 GHz ISM band with the isolation higher than 18 dB.
