  • Patent number: 9520640
    Abstract: Disclosed herein is a top load multi-band monopole antenna that is utilized with an integrated electromagnetic coupling feed wire and resonator combination achieving broad band and multi-band performance for multiple frequency spectrums. The top loaded monopole can utilize 450-520 MHz, 698 through 960 MHz and 1000 through 3000 MHz bands contiguously and simultaneously by implementation of the coupling feed wire and resonator combination. The electromagnetically coupled top load resonator in conjunction with the lower monopole resonator section matches impedance for both low frequency and high frequency range operation. A flexible radome housing structure augments impact resistance by permitting the monopole radiator aperture to flex under mechanical load while maintaining reliable signal transmission and reception properties.

  • Publication number: 20120169556
    Abstract: A top load multi-band monopole antenna is utilized with an integrated resonator to achieving broad band and multiband performance for multiple frequency spectrums. The top loaded monopole antenna can utilize a low frequency band (e.g., approximately 700/800/900 MHz) and a high frequency band (e.g., approximately 1900 MHz to approximately 1500 MHz) by implementation of the resonator. The resonator matches an impedance of the upper portion of the top loaded monopole antenna for capabilities in a high frequency range without interference from any low frequency range.

  • Patent number: 7091915
    Abstract: An antenna system operable to receive radio frequency signals and operable to couple radio frequency energy through a dielectric panel. The system includes an exterior radio frequency coupling module having a plate and a shield electrically coupled to the plate. The exterior coupling module also has a conductive member electrically isolated from the plate and the shield. The system also includes an interior radio frequency coupling module having a plate and a shield electrically coupled to the plate. The interior coupling module includes a conductive member electrically isolated from the outer conductor and a shield. The exterior coupling module is affixed to one side of the dielectric panel and the interior coupling module is affixed to another side of the dielectric panel in juxtaposition to the exterior module. Both conductive members of the exterior and interior module contact the dielectric panel.
