摘要： An antenna includes a first element, a second element, and a reactance-adjustable component. The first element receives an excitation current through an electrical connection to an antenna feeder, and the second element generates an induced current through electromagnetic induction of the first element. The reactance-adjustable component is disposed at an end of the first element close to a reference plane, and/or the reactance-adjustable component is disposed at an end of the second element close to a reference plane. The reference plane uses a connection point between the first element and the antenna feeder as an origin point and is perpendicular to an axial direction of the first element. The reactance-adjustable component has an adjustable reactance value and is configured to adjust a phase difference between an excitation current and an induced current, where the phase difference has an association relationship with a target angle of radiation of the antenna.

摘要： An antenna apparatus, which can increase capacity in a cellular communication system or Wireless Local Area Network (WLAN), such as an 802.11 network, operates in conjunction with a mobile subscriber unit or client station. At least one antenna element is active and located within multiple passive antenna elements. The passive antenna elements are coupled to selectable impedance components for phase control of re-radiated RF signals. Various techniques for determining the phase of each antenna element are supported to enable the antenna apparatus to direct an antenna beam pattern toward a base station or access point with maximum gain, and, consequently, maximum signal-to-noise ratio. By directionally receiving and transmitting signals, multipath fading is greatly reduced as well as intercell interference.

摘要： An antenna assembly includes at least two active or main radiating omni-directional antenna elements arranged with at least one beam control or passive antenna element used as a reflector. The beam control antenna element(s) may have multiple reactance elements that can electrically terminate it to adjust the input or output beam pattern(s) produced by the combination of the active antenna elements and the beam control antenna element(s). More specifically, the beam control antenna element(s) may be coupled to different terminating reactances to change beam characteristics, such as the directivity and angular beamwidth. Processing may be employed to select which terminating reactance to use. Consequently, the radiator pattern of the antenna can be more easily directed towards a specific target receiver/transmitter, reduce signal-to-noise interference levels, and/or increase gain by using Radio Frequency (RF), Intermediate Frequency (IF), or baseband processing. A Multiple-Input, Multiple-Output (MIMO) processing technique may be employed to operate the antenna assembly with simultaneous beam patterns.
