Diversity antenna with slits for WBAN applications

In this paper, a diversity antenna with slits for WBAN applications is proposed. The antenna consists of two T-shaped monopoles and three slits. Through three slits, a high isolation characteristic is achieved and the resonant frequency can be controlled. To analyze the antenna performance over a human body, the proposed antenna over a human equivalent flat phantom is investigated through simulation. A return loss characteristic of the antenna is insensitive to the existence of the phantom. The antenna operates in 2.4 GHz ISM band with the isolation higher than 23 dB.
