Investigation of the film antenna for wireless power transmission to the capsular endoscope

摘要

Recently, the wireless power transmission has been investigated for many applications such as capsular endoscope that exists for a long time in the body. They can reduce the burden of doctors and patients, on the other hand, they has the risk due to contain cell battery that might leak toxic substances. In this paper, we examine the way of wireless power transmission to a capsular endoscope by using microwave. We propose the planar antenna that can be easily produced and can be hard to deform. Using proposed antenna, we acquired good characteristics.
