【発明の詳細な説明】
この発明は、マイクロ波帯やミリ波帯で用いられる々向
性ろ波器の改良に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a directional filter used in microwave bands and millimeter wave bands.
ここでは説明を簡単にするために、三つの周波数に限定
し、この三つの周波数ｋ ｆｌｍ ｆｚ ＊ｆ３とし、
相互ＩＣｆ％＜ ｔ２＜ ｔｓの関係にあるものとして
説明する。Here, in order to simplify the explanation, we will limit it to three frequencies, and let these three frequencies be k flm fz *f3,
The explanation will be given assuming that there is a relationship of mutual ICf%<t2<ts.
そして、ここでは、上記三つの周波数帯から成る波から
ｆｔ０波を分波する場合について説明する。Here, a case will be described in which the f0 wave is separated from the waves consisting of the above three frequency bands.
ます、第１図忙示す従来の方向性ろ波器にっいて簡単に
説明する。First, the conventional directional filter shown in FIG. 1 will be briefly explained.
８１４１図において、（１）は主導波管、（２０ま副尋
波管’、 ＋３１ 、 ＋４１は円筒空胴共振器、（５
１〜（７）は結合孔。In Figure 8141, (1) is the main wave tube, (20 is the sub-wavelength tube', +31, +41 is the cylindrical cavity resonator, (5
1 to (7) are binding holes.
（２１の端子である。(This is the terminal number 21.
ここで、結合孔（５１、（７１ｋ工、主導波管（１）お
よび−導波管（２）の一端に入射した波が、空胴共振器
１３）お、よび空胴共振器１４１に円偏波で結合するよ
うな位［、形状で設けられているものとする。Here, the wave incident on one end of the coupling hole (51, (71k), main waveguide (1) and -waveguide (2) enters the cavity resonator 13) and the cavity resonator 141 in a circular manner. It shall be provided in such a shape that it will couple with polarized waves.
いま、主導波管（１１の端子Ｉ−にｆｌ ＊ ｆｔ ｗ
ｆｓの波を導入し、空胴共振器（３１，（４）の管軸

胴共振器（３）の影響を受けることなくそのまま通過し
、端子層に取り出される。 ｆｔの波は。Now, connect fl * ft w to the terminal I- of the main wave tube (11).
When a wave of fs is introduced and the tube axis length of the cavity resonator (31, (4) is selected to be approximately - of the tube wavelength of the frequency tif2), the wave is coupled with circular polarization by the coupling hole (5) K. The wave of ft resonates in the cavity resonator 131. The other waves of ft and fs pass through the cavity resonator (3) as they are without being affected and are taken out to the terminal layer.
さらに空胴共振器（４）で共振し、結合孔（７）を通し
て副尋波管＋２１ Ｋ結合する。このとき、空胴共振器
（４）中の波が円偏波であるので、可逆性から細尋波管
（２）に結合したｆｔ０波には方向性があり。Furthermore, it resonates in the cavity resonator (4) and is coupled to the sub-hybrid wave tube +21K through the coupling hole (7). At this time, since the wave in the cavity resonator (4) is a circularly polarized wave, the f0 wave coupled to the narrow wave tube (2) has directionality due to its reversibility.
端子ｌに取り出される。It is taken out to terminal l.
以上に述べたように、このような方向性ろ波器は１周波
数の異なる波を分波したり合成したりするいわゆる分波
器の機能を有している。As described above, such a directional filter has the function of a so-called demultiplexer that demultiplexes or combines waves of different frequencies.

, (7+ must be provided at a position where the magnitude of the tube axis direction component and the transverse direction component of the magnetic field in the main waveguide (1) and the sub waveguide (2i) are equal, and this position is the main waveguide +1 )
Since the position is close to the narrower wall surface of the sub-waveguide (2), the size of the Wj joint hole (51, 1?+) cannot be made large.
結合孔１５１ 、 （７１の結合量が小さく９分波する
で２０周波数帯域が狭帯域になるという欠点があった。There was a drawback that the coupling amount of the coupling holes 151 and 71 was small, and that the 20 frequency band became a narrow band when 9 waves were split.
この発明はこれらの欠点を除去するために。This invention aims to eliminate these drawbacks.
