での強固な抑圧により固定させている。Since the performance of a slot antenna depends on the accuracy of the arrangement of the horn and the slot waveguide, each component such as the horn should be required to have a certain size, but in practice it is important to consider manufacturing costs, etc. For example, they are manufactured with slight dimensional variations within a range that does not affect the above performance. Therefore, in order to maintain the consistency of the above-mentioned placement accuracy, we manufactured a horn with a fitting part slightly narrower than the size of the slot waveguide into which it is inserted, and in addition to the adhesive, It is fixed through strong oppression.

Furthermore, there is a risk that the slot waveguide may be deformed or damaged due to its narrow dimensions.

アンテナを提供するものである。This invention was made in view of the above, and the dimensions of the insertion part of the horn are made slightly wider in advance to improve workability during insertion and to have elasticity in order to maintain placement accuracy until adhesive fixing. The present invention provides a slot antenna having a structure in which a spacer is interposed.
以下、図面の実施例に基づいて説明する。The following description will be made based on the embodiments shown in the drawings.

ことができる。In the figure, 1 is a slot waveguide in which a slot (not shown) is formed in the upper surface S. Reference numeral 2 designates a horn into which the slot waveguide 1 is inserted and equipped. The width Lh of the recess 3 of the horn 2 is slightly wider than the width Ls of the slot waveguide 1. Reference numeral 4 denotes a spacer made of an elastic member having elasticity, for example, phosphor bronze, which is formed by bending a rectangular flat plate to a predetermined dimension, and has elastic pieces 5 at both ends. In order to fit the horn 2 into the recess 3, for example, a plurality of spacers 4 are adhesively arranged in advance at appropriate positions in the recess 3, and then the slot waveguide 1 coated with adhesive is applied to the elastic force of the elastic piece 5. This is done by pushing in against the pressure. Then, at least until the adhesive fixes the slot waveguide 1 and the horn 2, the bonding position of the two is maintained statically, and as a result, the placement accuracy can be maintained without wobbling.

By fine-tuning. It is possible to eliminate the above-mentioned variations and obtain a constant pressing force.
更に、該スペーサー４は底面を有する一体構造且つ小型
軽量であるから、固着するまでの間にずれる心配はなく
、又嵌入作業も極めて容易である。Further, since the spacer 4 has a one-piece structure with a bottom surface, is small and lightweight, there is no fear that it will shift until it is fixed, and the fitting operation is extremely easy.
