Abstract

A line bridging element for two microstrip lines, each of which are configured to conduct electromagnetic waves having a wavelength in the millimeter wavelength range, including a dielectric resonator, including a first coupling point, which is configured to couple the line-conducted electromagnetic wave, which is carried in the first microstrip line, into the dielectric resonator, including a second coupling point, which is configured to decouple the electromagnetic wave coupled into the dielectric resonator into the first microstrip line. The invention also provides a method for manufacturing a line bridging element.

First claim

What is claimed is:

1. A line bridging element for two microstrip lines, each of which is configured for conducting electromagnetic waves having a wavelength in the millimeter wavelength range, comprising:
a dielectric resonator;
one first coupling point to couple one first line-conducted electromagnetic wave, which is carried in the first microstrip line, into the dielectric resonator; and
one second coupling point to decouple the first electromagnetic wave coupled into the dielectric resonator from the dielectric resonator into the first microstrip line;
wherein the first microstrip line is interrupted between the first and the second coupling points, and
wherein the second microstrip line runs under the dielectric resonator, between the first and the second coupling points and across an entire width of a printed circuit board on which the first microstrip line, the second microstrip line, the first coupling point, and the second coupling points are arranged.

2. The line bridging element of claim 1 , wherein at least one of the first coupling point and the second coupling point widen(s) from the width of the first microstrip line to a predefined width in the direction of the resonator, to the width of the dielectric resonator.

3. The line bridging element of claim 1 , wherein the dielectric resonator is formed from a plastic.

4. The line bridging element of claim 1 , wherein the dielectric resonator is coated at least partially with metal.

5. The line bridging element of claim 1 , wherein the dielectric resonator includes solder pads which are solderable onto the printed circuit board and are configured to fix the dielectric resonator on the printed circuit board.

6. The line bridging element of claim 5 , wherein the solder pads are electrically coupled to the metal.

7. The line bridging element of claim 1 , wherein the dielectric resonator has one of a rectangular parallelepiped shape, a cubed shape, and a cylindrical shape.

8. The line bridging element of claim 1 , wherein at least one of the first coupling point and the second coupling point widen(s) from the width of the first microstrip line to a predefined width in the direction of the resonator.

9. A method for manufacturing a line bridging element for two microstrip lines, each of which are configured for conducting electromagnetic waves having a wavelength in the millimeter wavelength range, the method comprising:
arranging one first coupling point in the first microstrip line, which couples a first line-conducted electromagnetic wave carried in the first microstrip line, into a dielectric resonator;
arranging one second coupling point opposite the first coupling point, the second coupling point decoupling the electromagnetic wave coupled into the dielectric resonator from the dielectric resonator into the first microstrip line; and
arranging the dielectric resonator on top of the first coupling point and the second coupling point;
wherein the line bridging element includes:
the dielectric resonator;
the first coupling point to couple one first line-conducted electromagnetic wave, which is carried in the first microstrip line, into the dielectric resonator; and
the second coupling point to decouple the first electromagnetic wave coupled into the dielectric resonator from the dielectric resonator into the first microstrip line;

interrupting the first microstrip line between the first and the second coupling points; and
arranging the second microstrip line such that the second microstrip line runs under the dielectric resonator, between the first and the second coupling points and across an entire width of a printed circuit board on which the first microstrip line, the second microstrip line, the first coupling point, and the second coupling points are arranged.

10. The method of claim 9 , further comprising:
at least one of:
forming the dielectric resonator from a plastic having a rectangular parallelepiped shape, a cubed shaped or a cylindrical shape; and
coating the dielectric resonator at least partially with metal.

11. The method of claim 9 , further comprising:
arranging solder pads on the dielectric resonator, the dielectric resonator being fastened during arranging on the printed circuit board, by soldering the solder pads on the printed circuit board.

12. The method of claim 9 , further comprising:
forming at least one of the first coupling point and the second coupling point from the width of the first microstrip line up to a predefined width in the direction of the resonator, the predefined width corresponding to the width of the dielectric resonator.
