Abstract (en)
[origin: JPH0346403A] PURPOSE: To provide an optical plus matrix distributor having larger coupling and an application wide band by arranging asymmetric obstacles made of metallic studs on the inner surface of a sidewall of a guide so as to be formed on the longitudinal end of each conductive strip forming a main line. CONSTITUTION: This microwave energy distributor has a vertically opened guide constituted of parallel side walls 11, 12 forming a vertically hollow structure opened on one side face over the whole length. A load 16 for absorbing electromagnetic waves at the operation frequency is arranged on a rear part 13 in the hollow structure. Conductive strips 17, 18 like long plates are arranged on intermediate positions between sidewalls 11, 12 and asymmetric obstacles 19 to 22 consisting of metallic studs are arranged between respective strips 17, 18 and the insides of the sidewalls 11, 12 in the guide. These obstacles 19 to 22 are used for exciting a TEM mode to the aperture part from a TE mode propagated through the strips 17, 18.
