[0002]

2. Description of the Related Art A conventional technique will be described in detail with reference to the drawings.

FIGS. 4 (a) and 4 (b) are a perspective view and a front view showing an example of the related art. The main body 101 of the wireless device includes a rod antenna 101, a solar battery 105, and a secondary battery 1
04. (For example, Japanese Patent Application Laid-Open No. 7-22169)
The solar cell 105 can be separated from the main body 101. Since the extension cable 118 and the hook 119 can be used to set the solar cell 105 in a place where solar energy can be taken from the main body 101 placed in the breast pocket 120 (in which the sunlight is blocked), for example, a long standby time Even in this state, the secondary battery 104 can be recharged without exhausting it.

Next, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a partial sectional view showing one embodiment of the present invention. The solar cell mounted antenna 2 shown in FIG. 1 includes a mounting plate 7, a solar cell 6 mounted on the mounting plate 7, a conductor film 5 provided on the solar cell 6, and It is configured to include the provided array antenna element 4 and the protective glass 3 provided on the array antenna element 4.

FIG. 2 is a sectional view showing the details of the conductor film 5 shown in FIG. A light reflecting film 12 having the same optical anisotropy as a magic mirror is attached to the lower surface of a transparent film body 11, and a conductor film 10 is attached to the upper surface thereof.

A radio wave incident from the protective glass 3 is reflected by the conductor coating 10 and returns to the array antenna element 4.
Light incident from the protective glass 3 side passes through a conductor film 10 (trade name: Nesa glass or the like) transparent to light and a light reflecting film 12 having optical anisotropy to excite the solar cell 6. The light reflected from the solar cell 6 is reflected by the light reflecting film 12 and excites the solar cell 6 again.

FIG. 3 is a schematic perspective view showing an example of use of the present invention. The wireless device 1 is provided with a solar cell mounted antenna 2 which also functions as an upper lid, and has a desired angle θ.
Can be set to The angle θ is set to an optimal value for receiving a radio wave from a satellite to be communicated, but there is a sufficient probability that a part of sunlight can be received at that time. (It would be fine if the satellite and the sun were at the same altitude in the same direction)

[0012]

The solar cell mounted antenna of the present invention has an effect that the system area can be reduced because the antenna and the solar cell are integrated.
