Abstract: A headlight socket with an antenna includes a base, cover, first antenna device and connection stand. The base includes a mounting portion. The cover is mounted on the base through the mounting portion and has a sidewall for annularly defining a receiving space. The first antenna device is received in the cover and includes a conductive end. The connection stand is coupled to the sidewall. The connection stand includes a connection port in contact and connection with the conductive end. The headlight socket is mounted on a vehicle. The first antenna device for receiving signals is disposed at the front of the vehicle, thereby enhancing the quality of signal reception. Conventional vehicular antennas are integrated into the headlight socket to manifest advantages of modularization so that an automobile assembly process is simplified, allowing internal circuits to be readily integrated.

Abstract: A radio signal receiving system for providing a signal to a transceiver includes a signal retrieving module and a signal processing module. The signal retrieving module retrieves a radio signal through one of a conducting wire in an electrical outlet, a conducting wire in a vehicular cigarette lighter, and a metallic vehicular casing. The radio signal receiving system operates without any conventional self-contained antenna and includes a radio signal receiving carrier which is either made from a conventional conducting wire or made of a metal to thereby enhance the efficiency of signal reception.

Abstract: A mutually inductive resonant antenna receiving radio waves of dual frequency bands improves a conventional antenna series-connected to a uniaxial wire. The mutually inductive resonant antenna receives FM or TMC radio waves and comprises a first antenna and a second antenna. The first antenna has a first conductive core wire and a first insulating layer. The first insulating layer encloses the first conductive core wire. The second antenna has a second mesh-like conductive layer and a second insulating layer. The second mesh-like conductive layer encloses a section of the first antenna such that another section of the first antenna is exposed. The second insulating layer encloses the second mesh-like conductive layer. A section of the second mesh-like conductive layer is extended from the first antenna and electrically connected to a signal transmission line. The second mesh-like conductive layer is not in contact with the first conductive core wire.

Abstract: A digital broadcasting antenna structure includes a substrate having at least a first and a second face; a main antenna arranged on the first face; an amplifier arranged on the first face and electrically connected to the main antenna; a compensating unit arranged on the second face and electrically connected to the main antenna; a bandwidth modulating unit arranged on the second face and electrically connected to the compensating unit; and a grounding section arranged on the second face and electrically connected to the bandwidth modulating unit. The digital broadcasting antenna structure can receive digital broadcasting signals without being restricted to any specific receiving direction, and is applicable to low, intermediate and high frequency bands to therefore achieve the effects of miniaturization, high bandwidth and low return loss.
