A signal-of-interest is received by using a first and second planar electrically conductive disc to define an antenna. The antenna produces RF signal outputs at three output ports E, Eand E, each having a different associated gain pattern and polarization response. At least one null is automatically asserted in a pattern defined by the antenna in a specified direction by selectively weighting a gain and a phase of the RF signals respectively produced from the three output ports and then combining the RF signals to produce a first receiver signal output.

Compact receiver system with antijam and antispoof capability

A LORAN device may include a LORAN antenna, a LORAN receiver, an RF signal path extending between the LORAN antenna and the LORAN receiver and being subject to ambient RF interference, and an ambient RF interference canceller coupled in the RF signal path. The ambient RF interference canceller may include an ambient RF interference sensor configured to generate an estimated ambient RF interference signal based on the sensed ambient RF interference, and cancellation circuitry configured to cooperate with the ambient RF interference sensor to generate an ambient RF interference cancellation signal based upon the sensed ambient RF interference signal, and add the ambient RF interference cancellation signal to the RF signal path.
