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： A directive antenna operable in multiple frequency bands includes an active antenna element and at least one passive antenna element parasitically coupled to the active antenna element. The passive antenna element(s) have length and spacing substantially optimized to operate at (i) a fundamental frequency associated with the active antenna element and (ii) a higher resonant frequency related to the fundamental frequency. Spatial-harmonic current-distributions of the passive antenna elements are used to create the multiple frequency bands of operation. The directive antenna also includes devices operatively coupled to the passive antenna element(s) to steer an antenna beam formed by applying a signal at the fundamental resonant frequency, higher resonant frequency, or both to the active antenna element to operate in the multiple frequency bands.

摘要： A folded monopole antenna that supports lower and upper frequency bands may be used in CDMA, WLAN, or other wireless communications systems. The folded monopole antenna may be located in a handset next to a vertical ground plane. The folded monopole antenna may be folded at least twice and connected to the ground plane through a reactance. The dimensions of different sections of the folded monopole antenna define lower and upper frequency band characteristics, and an offset location of an input feed affects the bandwidth of the frequency bands. The reactance between the antenna and ground plane can be selected to fine tune the frequency bands. Various input feeds, including a co-planar waveguide, may be employed. Dynamically adjustable reactances may be used in the input feed and ground line for adapting the antenna to various environments.
