Latest Patents

Nielsen holds a patent for an "Interference rejection GPS antenna system." This invention relates to a method and apparatus for selectively receiving radio frequency (RF) signals. It utilizes an array of antenna elements, including a center antenna for receiving the RF signal. A navigational controller uses coordinate information to determine pointing vectors that direct the reception lobes towards respective RF signal sources. The beam-forming electronics connected to the antenna array and the navigational controller are responsible for forming these reception lobes. Each lobe points in the direction of a determined pointing vector. To ensure accurate and precise measurements, a constant phase center is maintained by adjusting the center antenna to the same phase shift for each lobe. The lobes are steered by adjusting the phase shift of the antenna elements surrounding the center antenna.
