Abstract

A feeding apparatus for a monopole antenna having a radiating unit and a grounding unit is for transmitting a multimedia signal to a multimedia player device coupled to the radiating unit. The feeding apparatus includes a first feeding unit coupled to an inner conductor of a coaxial cable for feeding the multimedia signal transmitted by the coaxial cable to the radiating unit, and a second feeding unit coupled to a conducting mesh of the coaxial cable for connecting to the grounding unit.

Claims

1. A feeding apparatus for a monopole antenna having a radiating unit and a grounding unit, for transmitting a multimedia signal to a multimedia player device coupled to the radiating unit, the feeding apparatus comprising:

a first feeding unit coupled to an inner conductor of a coaxial cable for feeding the multimedia signal transmitted by the coaxial cable to the radiating unit; and

a second feeding unit coupled to a conducting mesh of the coaxial cable for connecting to the grounding unit.

2. The feeding apparatus of claim 1, wherein the monopole antenna is a frequency modulation (FM) antenna, and the multimedia player device is a vehicle FM player device.

3. The feeding apparatus of claim 1, wherein the multimedia signal is an analog broadcast signal in an available FM frequency band and the analog broadcast signal is transformed from a digital satellite broadcast signal received by a digital satellite broadcast transformation device.

4. The feeding apparatus of claim 1, wherein the first feeding unit makes metal contact with the radiating unit in order to feed the multimedia signal to the radiating unit.

5. The feeding apparatus of claim 4, wherein the first feeding unit and the radiating unit are made of metal material.

6. The feeding apparatus of claim 1, wherein the second feeding unit makes metal contact with the grounding unit.

7. The feeding apparatus of claim 6, wherein the second feeding unit and the grounding unit are made of metal material.

8. The feeding apparatus of claim 1, wherein the first feeding unit and the radiating unit are ¼

wavelength open circuit transmission lines respectively.

9. The feeding apparatus of claim 1, wherein the second feeding unit and the grounding unit are ¼

wavelength open circuit transmission lines respectively.

10. The feeding apparatus of claim 1, wherein the first feeding unit feeds the multimedia signal to the radiating unit by using electromagnetic coupling.

11. The feeding apparatus of claim 1, wherein the second feeding unit is electromagnetically coupled to the grounding unit.
