Abstract

A wireless communication apparatus includes a first antenna, an antenna driving circuit, a first medium, a second medium, and a second antenna. The antenna driving circuit drives the first antenna. The first medium is electrically connected between the first antenna and the antenna driving circuit. The second medium and the first medium are in energy coupling. The second antenna is electrically connected with the second medium.

Claims

1. A wireless communication apparatus, comprising:

a first antenna;

an antenna driving circuit driving the first antenna;

a first medium electrically connected between the first antenna and the antenna driving circuit;

a second medium, wherein the first medium and the second medium are in energy coupling; and

a second antenna electrically connected with the second medium,

wherein a first transmission path is formed by the antenna driving circuit, the first medium and the first antenna, and a second transmission path is formed by the antenna driving circuit, the first medium, the second medium and the second antenna.

2. The wireless communication apparatus of claim 1, wherein the antenna driving circuit is electrically connected with the first antenna by a conductive unit.

3. The wireless communication apparatus of claim 2, wherein the conductive unit is a coaxial transmission line.

4. The wireless communication apparatus of claim 2, wherein the first medium is located between the conductive unit and the first antenna.

5. The wireless communication apparatus of claim 1, wherein the signal transmission distance of the first medium and the first antenna equals to ¼

of the operation wavelength of the first antenna.

6. The wireless communication apparatus of claim 1, further comprises:

a medium driving module connected with the second medium for driving the second medium to move toward or away from the first medium.

7. The wireless communication apparatus of claim 1, further comprises:

a medium driving module connected with the first medium for driving the first medium to move toward or away from the second medium.

8. The wireless communication apparatus of claim 1, further comprises:

a medium isolating element disposed between the first medium and the second medium for blocking the energy coupling between the first medium and the second medium.

9. The wireless communication apparatus of claim 8, further comprises:

a medium isolating driving module for driving the medium isolating element to move.

10. A wireless communication apparatus, comprising:

a first antenna;

an antenna driving circuit driving the first antenna;

a first medium electrically connected between the first antenna and the antenna driving circuit;

a second medium, wherein the first medium and the second medium are in energy coupling;
