摘要： A dual coupled vehicle glass mount antenna system and method. The inventive system is adapted for operation through any suitable partition, such as an automobile windshield, and comprises an antenna mounted on a first side of the partition for receiving a signal and a first circuit connected to the antenna. The antenna and the first circuit are mounted on a first side of the partition. In accordance with the present teachings, an arrangement is provided for supplying power to the first circuit. The output of the first circuit is coupled through the partition to a second circuit mounted on a second side thereof by a first coupling arrangement. In the illustrative embodiment, the antenna is a radio frequency antenna, the partition is a vehicle windshield, the first circuit is an amplifier, and the arrangement for supplying power is a second coupling arrangement. In the illustrative embodiment, the first and second coupling arrangements are coils and power is supplied to the second coupling arrangement from a direct current source by a cable. In alternative embodiments, power is supplied to the first circuit by a battery or solar cell arrangement. In the illustrative embodiment, the second circuit includes an impedance matching circuit and a transmitter or receiver depending upon the application. The location of the amplifier on the antenna side of the windshield reduces the noise figure of the system and provides improved gained relative to the conventional design.
