プがある。2. Description of the Related Art As a means for improving the antenna efficiency of a plane antenna, there is a method of reducing the loss of a feed line by using a triplate line. The basic configuration of this type of antenna is
As shown in FIG. 8, the ground conductor 1, the film substrate 4 on which the antenna circuit 3 is formed, and the slot plate 6 having the slot openings 5 are laminated and arranged with the lower dielectric 2 and the upper dielectric 2 ′ interposed therebetween. It is a thing. The structure of the radiating part is shown in FIG.

Since the radiation can be suppressed, it is useful as a method for constructing a highly efficient planar antenna.
The type of (a) has already been reported by the present inventors in Proposals B-102 and B-103 of the 1991 Spring National Convention of the Institute of Electronics, Information and Communication Engineers. In this type of antenna, it is important to keep the distance between the ground conductor 1 and the film substrate 4 and the slot plate 6 uniform, and as shown in FIG. It is common to hold down. Further, for low-frequency applications where the influence of the adhesive is small, a laminate using the adhesive as shown in FIG. 9B is also common.

ンテナの製造法を提供するものである。On the other hand, in such a triplate feed type planar antenna, when an antenna having an extremely high frequency band such as a millimeter wave band is constructed, the thickness of the dielectrics 2 and 2'is also extremely large. Since it is thin and weak in strength, stress is generated in the screwed portion of the slot plate 6 and floating occurs in the portion other than the screwed portion of the slot plate 6, and the directional characteristics of the antenna deteriorate due to the excitation phase error. There was a problem. Further, the method using the adhesive has a problem that the loss of the adhesive is large and the antenna gain is reduced at the current technical level. The present invention provides a method for manufacturing a triplate-fed planar antenna capable of maintaining a uniform holding distance between a ground conductor and a slot plate even in a high frequency band such as a millimeter wave band and realizing good antenna characteristics.
