【考案の詳細な説明】
この考案はホーンアンテナの改良に関するものであり、
さらにくわしくいえば、ホーンアンテナの内部に藍燥空
気を充填するために必要な気密窓の改良に関するもので
ある。[Detailed explanation of the invention] This invention relates to the improvement of a horn antenna.
More specifically, the present invention relates to an improvement in the airtight window necessary for filling the inside of the horn antenna with indigo drying air.
従来のホーンアンテナは、その開口部に平板寸たは円錐
形の誘電体の薄板を装着して内部を気密にすることが多
かった。Conventional horn antennas often have a flat or conical dielectric thin plate attached to their opening to make the inside airtight.
この場合、電気的にこの誘電体薄板からの反射を少なく
するためには波長に比べて十分薄くする必要があった。In this case, in order to reduce electrical reflection from this dielectric thin plate, it was necessary to make it sufficiently thin compared to the wavelength.
一方機械的には乾燥空気の加圧によって生ずる応力に対
して破壊しないだけの十分な強度を持っていなければな
らない。On the other hand, mechanically, it must have sufficient strength not to break under the stress caused by the pressurization of dry air.
このため電気的要求と機械的要求が逆であり、通常は電
気的性能を犠牲にしているという欠点があった。This has the disadvantage that the electrical and mechanical requirements are opposite, usually at the expense of electrical performance.
オた、反射が少なくてしかも機械的強度の大きいものと
して誘電体の薄板のかわりにサンドインチ板や半波長板
が使用されることもあるが、この場合には反射の少なく
なる周波数範囲が非常に狭いという欠点があった。Additionally, a sandwich plate or half-wave plate is sometimes used instead of a dielectric thin plate as a material with low reflection and high mechanical strength, but in this case, the frequency range where reflection is low is very limited. It had the disadvantage of being narrow.
この考案は前記した従来の欠点を解決するために、ホー
ンの内壁に沿って薄い誘電体板を装着することにより、
電気的には反射が少なく、しかも内部の乾燥空気加圧に
よる変形を押えることができ、強度的にも十分なものを
実現するものである。This invention solves the above-mentioned conventional drawbacks by attaching a thin dielectric plate along the inner wall of the horn.
It has little electrical reflection, can suppress deformation due to internal dry air pressure, and has sufficient strength.
以下図面に従ってこの考案の特徴とするホーンアンテナ
の気密窓について説明する。The airtight window of the horn antenna, which is a feature of this invention, will be explained below with reference to the drawings.
第１図および第２図は従来のホーンアンテナの一例を示
すものであり、図において１はホーン、２ａは平板状の
誘電体の薄板、２ｂは円錐形の誘電体の薄板、３はゴム
バッキング、４は押工枠、５は導波管である。Figures 1 and 2 show an example of a conventional horn antenna. In the figures, 1 is a horn, 2a is a flat dielectric thin plate, 2b is a conical dielectric thin plate, and 3 is a rubber backing. , 4 is a pressed frame, and 5 is a waveguide.
この場合は前記のように電気的に反射を少なくするため
に充分に薄い誘電体板２ａ、２ｂを使用するとホー７１
の内部に乾燥空気を充填するとその加圧力によって誘電
体の薄板２ａ 、２ｂが変形または破壊することになる
。In this case, if sufficiently thin dielectric plates 2a and 2b are used to reduce electrical reflection as described above, the hole 71
When dry air is filled inside the dielectric thin plates 2a and 2b, the dielectric thin plates 2a and 2b will be deformed or destroyed by the applied pressure.
第３図はこの考案の一実施例を示すものであり、図にお
いて２ｃはホーン１の内壁に沿って装着された誘電体の
薄板であり、その他については第１図および第２図と同
じである。FIG. 3 shows an embodiment of this invention, in which 2c is a dielectric thin plate attached along the inner wall of the horn 1, and other aspects are the same as in FIGS. 1 and 2. be.
この場合、誘電体板２ｃはホーン１の内壁に沿って装着
されているため、ホーン１の内部に乾燥空気を充填した
時、その加圧力により変形を生じようとしてもホーン１
の内壁で押えられて変形が起こりにくく、したがって実
際に変形するのは導波管５の開口の大きさに相当する部
分であり、これはホーン１の開口の大きさにくらべると
非常に小さくなるので、同じ乾燥空気の加圧力に耐える
ために必要な誘電体板２ｃの厚さは非常に薄くすること
ができる。In this case, since the dielectric plate 2c is attached along the inner wall of the horn 1, when the inside of the horn 1 is filled with dry air, even if the horn 1 tries to deform due to the pressing force, the horn 1
It is difficult for deformation to occur because it is pressed by the inner wall of the waveguide, and therefore, what actually deforms is a portion corresponding to the size of the aperture of the waveguide 5, which is very small compared to the size of the aperture of the horn 1. Therefore, the thickness of the dielectric plate 2c required to withstand the same pressing force of dry air can be made very thin.
このため、電気的な反射も非常に少なくなり、性能のす
ぐれたホーンアンテナが実現できる。Therefore, electrical reflections are also extremely reduced, making it possible to realize a horn antenna with excellent performance.
なおこの考案は円錐形、角錐形といったホーンの形状に
関係なく実現でき、さらに誘電板２ｃとホーン１の内壁
の間を全面または一部のみ接着することも可能であり、
簡単に実現できるので、その経済的効果は大きい。Note that this idea can be realized regardless of the shape of the horn, such as a conical shape or a pyramidal shape, and it is also possible to bond the entire surface or only a portion between the dielectric plate 2c and the inner wall of the horn 1.
Since it is easy to implement, its economic effects are large.
