  • Patent number: 5969688
    Abstract: An improved antenna for use with a hand-held, portable cellular telephone in the 800 to 900 megacycle range for greatly increasing the range and signal efficiency of transmission and receipt, eliminating dead spots, and for reducing or eliminating ground radiation on the user while the device is being used, wherein the antenna includes matched input impedance, a resonance circuit of capacitance and inductance, and a high impedance connected to the end of the antenna radiating element. The high impedance allows the device to be voltage-fed from a single element, altering the radiation pattern both for transmission and receipt.

  • Patent number: 4584587
    Abstract: A whip antenna system for surface vehicles or the like. The antenna system's tuner has an LC tank circuit, into whose inductor is inserted a coil that is connected to the vehicle's transmitter/receiver, the coil being field coupled to the tank circuit's inductor. The inserted coil provides sufficient reactance that the vehicle need not serve as a counterpoise, thus providing an antenna of comparable size but electrically less close to the ground (i.e. one that has better "seeing"), and useable with non-metallic vehicles (e.g. fiberglass boats).
