Abstract :
In this paper, an implanted CPW fed slot monopole antenna for ISM band applications is proposed. The antenna has a simple structure with low profile and is placed on human tissues like Muscle, Fat and Skin. The designed antenna is made compatible for implantation by embedding it in a FR4. The proposed antenna is simulated with help of method of moment´s software IE3D by assuming the predetermined dielectric constant for the human muscle tissue, fat and skin. The antenna works in the short distance communication band (Electronic Communications Committee approved the frequency band - 688 MHz) and Industrial, Scientific and Medical (ISM Bands, 2.43GHz). Simulated maximum gains attain -18dBi and -14.77dBi in the two desired frequency ranges, respectively. The return loss, VSWR, radiation pattern, Z-parameter and current distribution of these antennas were examined and characterized.
