Abstract

A miniature 2.45 GHz microstrip antenna based on the short pin technique is presented. The antenna is designated for implantable medical devices which have extreme stringent requirements on componentspsila sizes. Theoretical analysis and implementation details of the antenna are presented in this paper. Direct measurement results show that the antenna achieves an impedance bandwidth of 104 MHz and a maximum gain of about 0 dbi. Preliminary animal test has been carried out which has verified the effectiveness of this antenna when working inside animal bodies.
