Abstract

A high-frequency coupler used in communication of high frequency signals, which aims to provide a high-frequency coupler satisfying both constant communication quality and thinning. The high-frequency coupler includes a circuit board and a toroidal coil. The circuit board includes a first receiving passageway and a second receiving passageway. The toroidal coil extends through the first receiving passageway and the second receiving passageway between a first surface and a second surface of the circuit board. The toroidal coil orbits on both sides of the first surface and the second surface in a circular shape. The toroidal coil reverses an orbiting direction at a position substantially near a half of a length of the toroidal coil.

Claims

1. A high-frequency coupler comprising:

a circuit board having a first receiving passageway and a second receiving passageway; and

a toroidal coil extending through the first receiving passageway and the second receiving passageway between a first surface and a second surface of the circuit board while extending in a orbital pattern on both sides of the first surface and the second surface;

wherein an orbiting direction of the toroidal coil reverses at a position substantially near a half of a length of the toroidal coil.

2. The high-frequency coupler according to claim 1, wherein the length of the toroidal coil is half of a wave length of a signal passing through the coupler.

3. The high-frequency coupler according to claim 2, further comprising a microstrip extending along the circuit board and in parallel with the first and second surfaces, the microstrip connecting to one end of the toroidal coil.

4. The high-frequency coupler according to claim 1, further comprising a microstrip extending along the circuit board and in parallel with the first and second surfaces, the microstrip connecting to one end of the toroidal coil.

5. The high-frequency coupler according to claim 4, wherein the microstrip has a length being half of a wave length of a signal passing through the coupler.

6. The high-frequency coupler according to claim 5, wherein the one end of the toroidal coil connects to the microstrip at approximately a middle point of the microstrip.

7. The high-frequency coupler according to claim 4, wherein the one end of the toroidal coil connects to the microstrip at approximately a middle point of microstrip.

8. The high-frequency coupler according to claim 6, further comprising an antenna element extending in parallel with the first and second surfaces of the circuit board and along an orbital path about the toroidal coil.

9. The high-frequency coupler according to any of claim 1, further comprising an antenna element extending in parallel with the first and second surfaces of the circuit board and along an orbital path about the toroidal coil.
