Abstract

PURPOSE:To exclude the phase error and to improve the array effect, by drilling in the notch to the wide surface of a rectangular waveguide so that it is made with the same slope angle as the slot slope angle to the narrow surface of the rectangular waveguide toward the orthogonal direction to the guide axis. CONSTITUTION:The slot 3 is made on the narrow surface 4 of the rectangular waveguide 1 in a slope angle of theta, and the notch to the wide surface 5 is made with the slope angle theta to the direction orthogonal to the guide axis. The guide wall current by TE10 mode flowing in and out to the slot 3 has a slope angle of theta on the narrow surface 4 and flows to the slot 3 with the slope angle theta the same as the case with the narrow surface 4, if the depth D of notch is small at the wide surface 5. Accordingly, the slot 3 makes the same operation as the slot excited with the current flowing on one plane unidirectionally. Thus, the slot 3 contributes to the excitation due to the guide current flowing to the wide surface 5 and can improve the array effect by increasing the slot conductance.
