Abstract

PURPOSE:To make the power distributed to each branching waveguide different from each other by inserting a metallic triangular prism from an E or H plane of a branching section with an eccentricity from the center of the branching part. CONSTITUTION:The metallic prism 5 is inserted with a shift (x) from the center of the branching section 3. Then, the symmetry of the branching section 3 is lost, the power reflected on the branching section 3 and the metallic triangular prism 5 and inputted to the branching waveguides 2a, 2b is given much to the branching waveguide 2a and less to the branching waveguide 2b, resulting that the power distributed to the branching waveguides 2a, 2b is made different.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a power divider used in microwave and millimeter wave circuits.

FIGS. 1A and 1B are diagrams showing an example of a conventional power divider, in which the width of the waveguide is a and the height is lb.

In the figure, (1111 main waveguide, (2a) and (2b) are branch waveguides, 131&'L branch part, (4a) and (4
b) are the boundaries between the branch waveguides (2a) and (2b) and the branch part (3), respectively.

An example of a conventional power divider shown in FIGS. 1(a) and (b3).

From the boundaries (4a), (4b) of the branch waveguides (2a), (2b) and the branch part (3), the branch waveguides (2a), (2b) are connected, respectively.
a), (2b) Since the impedance seen by f is equal, the power input to the main waveguide (1) is transferred to the one-branch waveguide (
2a) and (2b).

However, in the conventional power divider, one branch waveguide (2a)
, (2b) has the disadvantage that the power cannot be varied.

This invention aims to eliminate such drawbacks.

E side of branch (3) or 2) 1 branch from H side (3)
), and the metal triangular prism is fully inserted to obtain an arbitrary lightning force distribution ratio.Hereinafter, embodiments of this invention will be described in detail. In addition.

In the embodiment, a metal triangular prism is inserted from the E side of the branch part (31), but the same applies to one where a metal triangular prism is inserted from the H side of the first branch part (3 ends).

Figure 2 (a), (1:+1 and Figure 3 (al,
(b)) 2 is a diagram of an embodiment of the present invention. In the figure, (5
) is a metal triangular prism inserted from the center of the 9-branch part (3) from the E plane of the bifurcation part (3), and x is the metal triangular prism (5) inserted from the center of the branch part (3). The amount of deviation, h, and wkt are quantities indicating the size of the metal triangular prism (5), which are the height and length of the metal triangular prism (5), respectively.

Figures 2(a) and (blct) are H-plane branch type power dividers, and Figures 3(a) and (b) are E-plane branch type power dividers.

To briefly explain the principle of the power divider according to this invention,
By inserting the metal triangular prism (5) offset from the center of the branch part (3), the symmetry of the first branch part (3:) is broken and the light is reflected by the second branch part +31 and the metal triangular prism (5). The power input to the branch waveguide (2a), (2b) is less in the branch waveguide (2a) and more in the two-branch waveguide (2b), and as a result, the power input to the ship branch waveguide (2a), (2b) is less. ) distributed lightning, the power is different.

FIG. 4 is based on an experimental study to fully explain the characteristics of the power divider according to the invention. The branch waveguide (2
It is a figure which shows the ratio P2/P1 of electric power p and IP2 distributed to a) and (2b). Branch waveguide (2a).

(2b) Power distributed to p1. Ratio of p2 P2/P1
teeth.

The branching portion of the metal triangular prism (5) increases according to the deviation amount It was confirmed that the ratio P2/P1 of the distributed power "+ m "2 is large.

Although the power divider using a T-branch has been described for 0 or more, it is not limited to a T-branch, but can be implemented similarly to a divine branch circuit. Further, although the rectangular waveguide has been described, the power divider according to the present invention can be applied to transmission lines such as other circular waveguides as well, as described above.

By inserting the metal triangular prism by deviating from the E plane or H plane of the full branch part from the center of the 0 branch part.

It is possible to configure a power divider that distributes different powers to each branch waveguide, and the resulting effect is significantly greater.
