摘要： Disclosed herein is an antenna system comprising a plurality of element antennas, a plurality of variable phase shifters and a plurality of variable amplitude type devices connected to the plurality of element antennas respectively, and an arithmetic unit used to perform the arithmetical operation of the excitation amplitude and phase for exciting each of the plurality of element antennas. The arithmetic unit includes the four means and performs the arithmetical operation of the excitation amplitude and phase used to define a desired radiation pattern composed by each of the element antennas with respect to a preset allowable variation width D of the excitation amplitude. Since the arithmetic unit serves to fix the excitation amplitude and perform the arithmetical operation of the excitation phase separately, the antenna system capable of performing the arithmetical operation of the excitation amplitude and phase for obtaining a desired radiation pattern with respect to the preset allowable variation width D of the excitation amplitude, and obtaining a desired radiation pattern even when the allowable variation width D of the excitation amplitude is given, can be realized.

摘要： An antenna system includes a reflector and a primary and a subsidiary array antenna which are disposed in front of an aperture of the reflector so as to be positioned back-to-back with each other. An electric power which is supplied to the primary array antenna is also partly supplied to the subsidiary array antenna after it has been controlled in both phase and amplitude in order that a radiant beam from the subsidiary array antenna compensates for that portion of a secondary radiant beam from the reflector which is blocked by the primary array antenna. For example, a transmission source is connected to the primary array antenna through a coupler and a distributor while the coupler is connected to the subsidiary array antenna through a phase and an amplitude regulator and a distributor. The source may also be connected via the distributor to the primary array antenna formed of a plurality of radiating elements which are respectively connected to corresponding radiating elements of the subsidiary array antenna through couplers and delay lines or feeder lines.

摘要： An array antenna system and a method of exciting an array antenna wherein antenna elements are arranged on a curved surface. A desired radiation pattern with an undesirable sidelobe being suppressed is provided by compensating for the irregular density of antenna elements and by matching the null positions of the actual radiation pattern and an ideal Taylor radiation pattern.

摘要： Disclosed is an antenna system having a first antenna directed to receive a desired signal wave and a second antenna directed to receive only an interference signal wave superposed on the desired signal wave. Both signals received by the first and second antennas are combined and the amplitude and phase shift necessary for the second antenna signal to cancel the interference signal component existing in the first antenna signal is calculated from the combined signal. By combining the controlled second antenna signal with the first antenna signal, the desired reception signal having an improved S/N ratio can be obtained.
