Control of the fresnel maximum of an aperture antenna

  • US Patent No. 7295164
  • Issued: November 13, 2007
  • Status: Expired

The maximum peak power density of an aperture antenna that occurs in the near field region relative to the average power density concentration at other ranges within the entire near field is increased by lowering the aspect ratio of the aperture antenna, whereby the transmitter power can be increased and the operating range and performance of the system improved for applications that operate in the near field.
