Embodiment Construction

[0030] Hereinafter, preferred embodiments of the waveguide power divider and its manufacturing method of the present invention will be described in detail with reference to the accompanying drawings.

[0031] figure 1 It is a front view showing an example of a waveguide slot array antenna using a waveguide power divider. figure 2 yes figure 1 Side view of the waveguide slot array antenna shown.

[0032] figure 1 and figure 2 The shown waveguide slot array antenna consists of radiating waveguides 2 and 3 with a radiating slot 1 arranged on one wide wall surface (front side), and a power supply circuit 4 supplying power to the radiating waveguides 2 and 3 from the other wide wall surface (back surface). . exist figure 1 , figure 2 In , an example is shown in which two radiation waveguides are used, but there may be an odd number of radiation waveguides.

[0033] The radiation waveguide 2 and the power supply circuit 4 are electromagnetically connected via a coupli...

Abstract

A coupling slot 10 provided in a wide wall shared by a first rectangular waveguide 8 and a second rectangular waveguide 9 arranged by stacking is formed by directing a longitudinal direction of the coupling slot 10 to a tube axial direction, and a matching conductor 11 projecting to a waveguide near the coupling slot 10 is provided on one sidewall of the second rectangular waveguide 9. A process of providing the matching conductor 11 is easy, a structure that can be manufactured at low cost is obtained, and a power distribution ratio can be set at an arbitrary ratio.

Description

technical field [0001] The present invention relates to a waveguide power divider used in distributing or synthesizing microwave and millimeter wave electromagnetic waves and its manufacturing method. Background technique [0002] It is expected that the waveguide power divider used in the power supply circuit of the array antenna can set the power division ratio to an arbitrary ratio. As a conventional waveguide power divider that meets this requirement, for example, the waveguide power divider disclosed in Patent Document 1 is known. [0003] That is, the conventional waveguide power divider capable of setting the power distribution ratio to an arbitrary ratio is configured such that the first square waveguide (13) and the second square waveguide (12) are stacked in parallel, and the two The first waveguide is connected with a coupling window (14) whose longitudinal direction is perpendicular to the tube axis, and a thin-walled part (15) with a low height is arranged in t...
