  • Publication number: 20150002343
    Abstract: A pole-type vehicle antenna is provided that is mounted to a vehicle for the purpose of mobile services. In the vehicle antenna, a new type antenna for mobile services that substitutes for an antenna pole in a breakdown of the antenna pole is implemented by providing a fastening type preliminary antenna that performs antenna functions for mobile services inside an antenna case. Therefore, when the antenna is broken, a driver does not feel inconvenient in using mobile services.

  • Publication number: 20150002342
    Abstract: A pole-type vehicle antenna is provided that is mounted to a vehicle for the purpose of mobile services. In the vehicle antenna, a new type antenna for mobile services that substitutes for an antenna pole in a breakdown of the antenna pole is implemented by providing a thin film type preliminary antenna that performs antenna functions for mobile services inside an antenna case. Therefore, when the antenna is broken, a driver does not feel inconvenient in using mobile services.

  • Patent number: 8537060
    Abstract: A glass antenna of a vehicle is provided, in which the pattern of the antenna is positioned at the sealant provided between a window glass and the vehicle body for indirect grounding. With this, the impedance characteristic and reception level of the antenna can be increased in a cost-effective way.

  • Patent number: 8126413
    Abstract: A vehicle antenna includes a first Automatic Gain Control (AGC) unit and a second AGC unit. The first AGC unit may attenuate an input signal based on the strength of the input signal, and then output the attenuated signal to a transistor. The second AGC unit may control a power to be supplied or not to the transistor using a switching function based on the strength of the input signal. With the antenna, the signals of a strong electric field as well as the signals of a weak electric field adjacent to the strong electric field can be effectively controlled.

  • Publication number: 20100265145
    Abstract: An integrated antenna system for a car and a manufacturing method thereof are provided. The system includes: a base in which a first antenna and an antenna reception circuit installed; and a support which is installed in an upper portion of the base and implemented in a form of cylinder or polygonal barrel in such a manner that the antenna reception circuit and the first antenna are located in the inside thereof, wherein a second antenna is wound up in a spiral form on an inner and/or outer circumference of the support. The system provides a greater degree of freedom of design without reducing performance of the antenna system.
