Antennas in Medical Applications

Antennas used in microwave medical applications is discussed in this paper. In particular, the antennas for hyperthermia, biotelemetry and microwave imaging are covered in this paper. Design and optimization of antenna parameter is very crucial topic for design of antenna in medical application as in medical applications the antennas are placed very near to a patient's body and hence the effect of body on the performance of antenna is a additional parameter in these such antennas while selecting the material to fabricate these antennas. The development in antenna study confirms that there are wide efforts have been taken to improve these systems. Microwave imaging is a non-ionizing method which promises the ability of depth-scanning different dielectric bodies for biomedical applications. This method has been proved able to detect malignant tumors as the dielectric properties of these differ from other human tissues. Different microwave antennas used in medical imaging applications are discussed in this paper.
