Title: Antenna device
Inventor: KATAKI TAKASHI
IPC: H01Q25/02
Filed: 1981-07-29
Abstract: PURPOSE:To eliminate the effect of an undesired wave in a short time, by composing a  zero point having the directivity in the arriving direction of a desired wave and then  compounding a zero point of a radiation pattern to the angle in the arriving direction  of the undesired wave detected by scanning a main beam. CONSTITUTION:The interference of an undesired wave is first detected by a detecting  circuit 8 in case when the arriving direction is known for a desired wave. If the interference is detected, a judging circuit 9 applies a judging signal to an angle indicating  circuit 10 to detect the arriving direction of the undesired wave. The circuit 1 indicates  the arriving direction thetaS of the desired wave and an optional angle thetaN1 other than thetaS  to the next arithmetic circuit 12. The circuit 12 forms a zero point in the direction thetaS based on the above-mentioned judging signal and an angle indication and then calculates an oscillating distribution to form a main beam to the angle thetaN1. The circuit 10  replaces successively the angle thetaN1 and detects the angle thetaN1 in the arriving direction of the undesired wave where the electric power received at a signal receiver 7 is minimum. For a radiation pattern obtained under such conditions, the main beam is turned  toward the desired wave and zero point is composed in the arriving direction of the  undesired wave. As a result, the effect of the undesired wave can be eliminated.
