Embodiment Construction
[0032] In order to have a clearer understanding of the technical solutions, objectives and effects of the present invention, the specific implementation manners of the present invention will now be described with reference to the accompanying drawings.
[0033] figure 1 , 2 It shows the first preferred embodiment of the FM antenna structure of the present invention, which is essentially a FM car shark fin antenna for receiving FM signals. In more detail, the FM antenna structure of the present invention includes a shark-fin-shaped housing 1, a circuit board 2 disposed in the shark-fin-shaped housing 1, a wire-wound coil antenna 3 connected to the circuit board 2, and A solid material4. One surface of the circuit board 2 has a conductive pad 20, and the wound coil antenna 3 is used to collect radio signals with a predetermined bandwidth, and in this embodiment is used to collect FM signals. Wherein, a front end 30 of the wire-wound coil antenna 3 is soldered to the conductiv...
