Abstract: A capsule type medical device having a substrate section that includes at least a single layer substrate; an antenna conductor that is arranged on and closely attached to at least one surface of the substrate section; a transmitting circuit that is arranged on the one surface of the substrate section within an area surrounded by the antenna conductor; and a plurality of lands that are arranged to another surface of the substrate section, and electrically connected with the transmitting circuit.

Abstract: An antenna unit includes a receiving antenna which receives in-vivo information of a subject transmitted from a capsule medical apparatus, a wireless-signal generator which receives the in-vivo information of the subject received by the receiving antenna and generates a wireless signal including the received in-vivo information, a power supply unit which supplies power for the wireless signal generator, an outer covering on which the receiving antenna, the wireless-signal generator, the transmitting antenna, and the power supply unit are mounted. The power supply unit is flexible and can be transformed easily according to transformation of the outer covering.

Abstract: A medical system includes a capsule type medical apparatus introduced into a subject and having an antenna having directionality and a communication unit which executes a communication through the antenna, an external antenna, which is disposed outside of the subject and has an antenna having directionality and an antenna disposed together with the antenna and having directionality in a direction different from the antenna, and an external machine having a selection unit which selects any of the antennas in the external antenna and a second communication unit which executes a communication with the first communication unit through the antenna whose polarized wave surface is selected by the selection unit.

Abstract: A capsule medical apparatus is a capsule medical apparatus which floats on a liquid surface of liquid introduced into a subject and includes at least one in-vivo information obtaining unit, a transmitting unit, and a capsule-type casing. The at least one in-vivo information obtaining unit obtains the in-vivo information of the subject. The transmitting unit wirelessly transmits an electric wave including the in-vivo information obtained by the at least one in-vivo information obtaining unit to outside through the transmitting antenna. The capsule-type casing has the at least one in-vivo information obtaining unit, the transmitting antenna, and the transmitting unit, fixedly arranged therein. The transmitting antenna is arranged on a liquid surface position of the liquid when a part of the capsule-type casing floats on the liquid surface of the liquid.

Abstract: An antenna to be embedded in a capsule type medical device. The antenna includes an antenna conductor, and a sheet-like antenna substrate which at least partly electrically contacts with the antenna conductor. The antenna is formed by closely attaching the antenna conductor and the sheet-like antenna substrate.
