Abstract :
In this paper, the on-body performance of Higher Mode Microstrip Patch Antenna (HMMPA) antennas was investigated by measuring path gain S21 between two devices mounted on tissue-equivalent numerical and experimental phantoms, representative of human arm at 2.45 GHz. In particular, the study focused on the performance of a compact slotted (HMMPA). This antenna has a sufficient bandwidth for the operating requirements of the 2.45-GHz industrial, scientific, and medical (ISM) band and both antennas offered higher path gain compared to a fundamental-mode microstrip patch antenna. The overall dimensions of the proposed antenna are 37*37 mm. The influence of patient´s arm movements on the radio channel has been simulated and measured.
