Comprehensive Study of Printed Antennas on Human Body for Medical Applications

Biomedical industry is in continuous growth in the last few years. Compact antennas are crucial in the development of biomedical systems on human body. The interaction between printed antennas and human body has been investigated in this paper. Antennas electrical performance is altered significantly in vicinity to human body. This paper presents the performance of several printed antennas as a function of the distance from human body. Several new wideband printed antennas that operate in vicinity to human body are also presented in this paper.Tuneable antennas may be used to compensate variations in the antenna resonant frequency at different locations on the human body.If the air spacing between the new antenna and the human body is increased from 0mm to 5mm, the antenna resonant frequency is shifted by 5%.
