Patent ID: 8016756

Claim:
A medical system comprising: a capsule type medical apparatus that is introduced into a subject and includes a first antenna which outputs a radio wave having directionality in a first polarized wave direction and a first communication unit which executes a communication through the first antenna; an external antenna that is disposed outside of the subject and includes a second antenna having directionality to a second polarized wave direction and a third antenna that is disposed together with the second antenna and has directionality to a third polarized wave direction different from the second polarized wave direction of the second antenna; and an external machine that includes a selection unit which selects any of the second and third antennas and a second communication unit which executes a communication with the first communication unit through the external antenna whose plane of polarization is selected by the selection unit, wherein the external antenna includes a board of a monolayer or multilayer structure on which the second and third antennas are formed, and the second antenna and the third antenna are formed on different planes or different layers in the board.
