Abstract

A novel miniaturized Slot Antenna is proposed at 2.4 GHz Industrial, Scientific, and Medical band applications especially for bio medical applications. By properly positioning the feed and slots, proximity coupled feeding technique can be realized. Through optimization, a really compact size of 10 mm x 10 mm x 1.5 mm is achieved. The simulated results show that a narrow bandwidth of 2.393 - 2.410 at -10 dB for FR4 (εr = 4.4) substrate. The simulated results show that a narrow bandwidth can be realized with ǀ S11ǀ below -10 dB and axial ratio above 4 dB. Additionally, Total Gain, Directivity is found to be good enabling to be implemented for biomedical devices. Proximity coupled feeding technique ensures no radiation problems to the skin of the patient. Furthermore, the Linear Polarization and small size enables the antenna's reliability with the Receiver Antenna due to its liberty to be placed at any positions. Thus, the results show that the desired ISM band can be well covered and size of the proposed antenna is found to be accurate for many future ISM band bio-medical applications with best output values and performances.
