Directional Radio-Signal-Detection Apparatus And Methods Of Use
US Patent:
2012024, Oct 4, 2012
Filed:
Mar 29, 2011
Appl. No.:
13/394722
Inventors:
Son Nguyen - Westminster CO, US
International Classification:
G01S 3/14
US Classification:
342442
Abstract:
An apparatus for direction-finding a received radio signal is disclosed. The receiving apparatus selectively receives on a predetermined frequency to match the transmitter frequency. The receiving apparatus comprises of two or three antennas, including one or two loop antennas that work in conjunction with a third reference antenna (whose phase does not vary when its orientation changes relative to the transmitter), such as a dipole, monopole or helical antenna. By comparing the phase between the antennas the direction of the incoming RF signal can be determined. In some embodiments, the windings of the two loop antennas are wound in reverse with respect to each other in order to substantially double the sensitivity of the signal-detection capabilities.
Directional Radio Signal Detection Apparatus Using A Sense And Loop Antennas
US Patent:
2014004, Feb 20, 2014
Filed:
Aug 15, 2012
Appl. No.:
13/586172
Inventors:
Son Nguyen - Westminster CO, US
International Classification:
G01S 3/02
US Classification:
342448
Abstract:
An apparatus for direction finding a received radio signal is enclosed. The receiving apparatus selectively receives on a predetermined frequency to match the transmitter frequency. The receiving apparatus is comprised of one non directional antenna and two or more loop antennas. The loop antennas modify the field of the incident radio signal by absorbing the incident radio frequency energy to create a non-ambiguous gain pattern on the sense antenna that can be used to determine the direction of the incident RF signal.
