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 apparatus arranged in accordance with the invention has a plurality of element antennas 1 arranged on a plurality of concentric circles 2 assumed to exist on a plane and differs in radius from each other, and forms a beam in a direction inclined by &thgr;0 at the maximum from a direction perpendicular to the plane. If the radius of the n-th concentric circle 2 from the inner side is an; the number of element antennas 1 arranged on the n-th concentric circle 2 from the inner side is Mn, and the number of waves is k, the number Mn of element antennas 1 arranged on each concentric circle 2 is determined so as to satisfy the following equation: Mn+0.8·Mn1/3>k·an·(1+sin &thgr;0) Also, the element antennas 1 are arranged on each concentric circle 2 by being generally equally spaced apart from each other in the circumferential direction of the concentric circle.

摘要： When the portable wireless device of the present invention is used, the second housing 3 with the antenna unit 4 telescopically received therein is turned about the hinge 2 to a spread position where the antenna unit 4 is spread out a sufficient distance away from the housing 1 and is extended from the second housing 3. Hence, during communication the antenna unit 4 is kept sufficiently far apart from the user's head 100 to provide improved transmission and/or reception characteristics.

摘要： Since adaptive control has been made by using different reference characters every transmitter-receiver, it has been necessary to provide an adaptive control device every transmitter-receiver. Hereupon, an adaptive array antenna apparatus according to the invention provides a weighting control device for calculating a weight coefficient to control weighting processing so that electric power of array signals synthesized by applying weighting processing to signals received by antennas of a plurality of systems becomes minimum, and an adaptive control device for using the weight coefficient for application of weighting processing to thereby form null points of antenna directivity in a direction, along which interference signals having a greater electric power than that of desired signals arrive, to remove the interference signals and to output array signals to transmitter-receivers.

摘要： A composite antenna apparatus comprising a balun connected to an inner conductor at the upper end of a coaxial line 11, one end of a helical element formed by a pair of wire conductors is connected to the balun, the other end is wound symmetrically around the coaxial line using the the coaxial line as a center so as to face the balun and is connected to the outer conductor 13 at the lower end of the coaxial line. The provision of an outer conductor connecting terminal connected to the outer conductor and an inner conductor connecting terminal connected to the inner conductor at the lower end of the coaxial line, allows the formation, on the same axis, of a helical antenna fed by the coaxial line via the helical element and a monopole antenna formed by the outer conductor of the coaxial line. Thereby equivalent gain in the horizontal plane and a reduction in the occupied volume is achieved.

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.
