摘要：
The propagation loss between a capsule antenna inside a human body phantom and an outside antenna is investigated experimentally. The position estimation of a capsule antenna is also performed by using the received power distribution on a plane located outside phantom. Two frequency band of 320 MHz and 1 GHz are compared. For 320 MHz, a print monopole antenna with a capsule inside a human body phantom is designed and an inductor is used for impedance matching. It is found that there is a relation of tradeoff between the received power and the accuracy of the position estimation a capsule.
