Document Type and Number:
Japanese Patent JP2008178447
Kind Code:
A
Abstract:
To provide an in vivo device with high radiation characteristics not to be affected by in vivo antenna arrangement without enlarging an in vivo antenna element.
The in vivo device 100 to be arranged inside a living body comprises a monopole element 101 loaded on the in vivo device 100 and a parasitic element 104 arranged outside the living body closely to the monopole element 101. By the configuration, since the monopole element 101 and the passive element 104 are capacitively coupled and the parasitic element 104 is operated as an antenna element, antenna performance is increased. Thus, the monopole element 101 arranged inside the living body is reduced in size and burdens on the living body are reduced.
