Description
この発明によれば、管壁にスロットが設けられている導波管内部を、その内部を伝搬する電磁波の電界面と平行に導体壁でスロットを一列あるいは複数列毎に仕切ることで第２の方向（X軸）に複数配置したサブアレーでアンテナ開口を構成できるため、各サブアレーを所望の励振振幅・位相で励振できると共に、磁界面方向のスロット間結合を低減できる効果が得られる。さらに、各スロットへの励振方向は指向方向の異なるビームによらず各結合孔で一定［第１の方向（Y軸）］であるため、XZ面内から指向方向が外れることなくビーム走査できる効果も得られる。 According to the present invention, the inside of the waveguide provided with the slot in the tube wall is divided by the conductor wall into one or a plurality of rows in parallel with the electric field surface of the electromagnetic wave propagating in the inside. Since the antenna aperture can be configured by a plurality of subarrays arranged in the direction (X axis), each subarray can be excited with a desired excitation amplitude and phase, and an effect of reducing interslot coupling in the magnetic field direction can be obtained. Furthermore, since the excitation direction to each slot is constant [first direction (Y axis)] in each coupling hole regardless of beams different in directivity direction, beam scanning can be performed without deviation of the directivity direction from within the XZ plane. Can also be obtained.
