造が複雑化され実際上はほとんど不可能に近い。However, the conventional example 10 has a structure in which the transmission / reception device body (wireless device) 14 is arranged on the rear surface side of the reflecting mirror 11 so as to be separated from the primary radiator 13, and these are connected via the connection cable 21. Therefore, there is a problem that the connection loss (cable loss) is large, and there is a problem that the assembling work is troublesome. Furthermore, it is necessary to provide a heat radiating means for radiating the heat generated by the heat generating element in the device main body 14. is there. Although the problem of this connection loss can be solved by directly connecting the transmitter / receiver body 14 to the rear end of the primary radiator 13 (on the front side of the antenna device 10),
On the other hand, the transmitter / receiver body 14 in the direction of the central axis α
Since the projected area of the reflection surface 11a on the reflection surface 11a is large, the effective reflection area of the reflection surface 11a is reduced, and the antenna gain is reduced. Therefore, in order to reduce the projected area of the transmission / reception device 14 (that is, the electromagnetic wave shielding area), for example, the cross-sectional area (the central axis α
It is necessary to form a long cylindrical body having a small area (a surface orthogonal to the) to form a housing for the transmitter / receiver and mount the transmitter / receiver and the like therein. However, in such a long cylindrical housing, it is very difficult to mount each element, and the internal structure is complicated, which is practically impossible.
