Abstract

The aim of this study is to develop an animal exposure system for investigating biological effects of local exposure to microwaves from mobile phones. Currently, new mobile communication systems using a 3.4 GHz band are being developed. In this paper, an exposure system using a rectangular loop antenna is proposed for investigating the biological effects of microwaves in the 3.4 GHz band. The proposed antenna has a simple structure and can be tuned to a resonant frequency between 3.3 and 3.8 GHz by changing the feed point. Numerical dosimetry result shows good locality for 2-4 week-old rat model.
