Abstract
A GNSS active antenna with improved performance in the presence of interfering signals is described. The GNSS active antenna meets the requirements of DO-301 for Airborne GNSS antennas when in normal operation. The GNSS active antenna also generates a low elevation null steered to any azimuth angle when in an environment with an interfering signal. The null has minimal performance impacts at higher elevation angles near zenith. The GNSS active antenna includes a right-hand circular polarized microstrip antenna with a concentric vertically polarized monopole antenna. The GNSS active antenna also meets the requirements of ARINC 743 antenna outline and mounting hole pattern.
