Antenna unit and planar wireless device
First Claim
1. An antenna unit, comprising:
- a grounded planar antenna including a radiating element and a ground plate; and
a thin-film battery including a positive-electrode current collector opposing a negative-electrode current collector which is formed by the ground plate,wherein the ground plate and the positive-electrode current collector are overlapped, andwherein the radiating element and the positive-electrode current collector are not overlapped.

Abstract
An object of the present invention is to provide a planar type antenna unit and a planar type wireless device capable of reducing a projecting area of the wireless device. To achieve the above object, the planar type wireless device of the present invention is provided with a grounded planar antenna 10 which includes a radiating element 11 and a ground plate 12, a thin-film battery 20 which includes a positive-electrode current collector 21 opposing a negative-electrode current collector which is formed by the ground plate 12, and a transmitter/receiver IC arranged at a power feeding point 13 of the grounded planar antenna 10 and including a transmitter-receiver circuit which receives power from the negative-electrode current collector of the thin-film battery 20 and the positive-electrode current collector 21 of the thin-film battery 20, and transmits and receives signals by operating the radiating element 11 of the grounded planar antenna 10.
