摘要： An antenna for controlling a beam direction both in azimuth and elevation is disclosed. An antenna comprises a ground plane, at least one active element, and a plurality of passive elements. Both an upper half and a lower half of the passive elements are connected to the ground plane with variable reactive loads, whereby elevation angle of the radio beam is controlled by adjusting the variable reactive loads. Alternatively, an antenna may comprise a radio frequency (RF) choke coupled to the ground plane, whereby an elevation angle of the radio beam is controlled by controlling the RF choke. Alternatively, an antenna comprises a variable lens for changing a wave front of a radio wave which is passing through the variable lens, whereby the beam width and direction are controlled by the variable lens.

摘要： A wireless communication method and antenna system for determining the direction of arrival (DOA) of received signals in azimuth and elevation, (i.e., in three dimensions), to form a beam for transmitting and receiving signals. The system includes two antenna arrays, each having a plurality of antenna elements, two first stage multi-mode-port matrices, at least one second stage multi-mode-port matrix, an azimuth phase detector, an elevation amplitude detector, a plurality of phase shifters and a transceiver. The antenna arrays and the first stage multi-mode-port matrices form a plurality of orthogonal omni-directional modes. Each of the modes has a characteristic phase set. Two of the modes' phases are used to determine DOA in azimuth. The second stage multi-mode-port matrix forms a sum-mode and a difference-mode used to determine the DOA of the received signals in elevation. A beam is formed in the direction of the received signals by adjusting the phase shifters.

摘要： A matrix-fed circular array system includes a plurality of antennas, a plurality of azimuth matrices in communication with the antennas, and a plurality of elevation matrices in communication with the azimuth matrices. The array system forms M×N beams, where M is the number of azimuth beams, and N is the number of elevation beams. In another embodiment, through the use of a Shelton-Butler or Butler matrix which includes a plurality of hybrids, the system outputs omni-directional pancake-shaped radiation patterns that are isolated from each other when a communication signal is input into the system. In yet another embodiment, the system uses a beam forming network including two Shelton-Butler matrices. A first one of the Shelton-Butler matrices creates omni-directional pancake beams that are isolated from each other, and a second Shelton-Butler matrix creates multiple directive beams in an azimuth plane.

摘要： Wireless portable electronic devices such as laptop computers are provided with cavity-backed monopole antennas. A wireless device may have a housing. Conductive portions of the housing such as a conductive outer metal layer and internal frame structures may form a cavity having conductive walls. An antenna resonating element structure may be formed from monopole antenna resonating element arms of dissimilar lengths. One of the arms may be straight and another of the arms may be implemented using a meandering path. The antenna resonating element may be mounted over the cavity to form a cavity-backed monopole antenna. A display within the device may be covered by a cover glass. An opaque bezel region around the periphery of the cover glass may cover the antenna and block it from view. The antenna resonating element arms may run parallel to the longitudinal axis of the cavity.

摘要： An inverted-F antenna is provided that has a resonating element arm and a ground element. A shorting branch of the resonating element arm shorts the resonating element arm to the ground element. An antenna feed that receives a transmission line is coupled to the resonating element arm and the ground element. One or more impedance discontinuity structures are formed along the resonating element arm at locations that are between the shorting branch and the antenna feed. The impedance discontinuity structures may include shorting structures and capacitance discontinuity structures. The impedance discontinuity structures may be formed by off-axis vertical conductors such as vias that pass through a dielectric layer separating the antenna resonating element arm from the ground element. Capacitance discontinuity structures may be formed from hollowed portions of the dielectric or other dielectric portions with a dielectric constant that differs from that of the dielectric layer.

摘要： Slot antennas are provided for electronic devices such as portable electronic devices. The slot antennas may have a dielectric-filled slot that is formed in a ground plane element. The ground plane element may be formed from part of a conductive device housing. The slot may have one or more holes at its ends. The holes may affect the impedance characteristics of the slot antennas so that the length of the slot antennas may be reduced. For example, the holes can be used to synthesize the impedance of the slot antennas so that the slot antennas have a resonant frequency that is different from their natural resonant frequency. The holes may affect the impedance of the slot antennas in multiple radio-frequency bands.
