摘要： An antenna array that uses at least two passive antennas and one active antenna disposed above a ground plane, but electrically isolated from the ground plane, and a respective resonant strip positioned beneath each passive antenna. The passive antenna elements are positioned about the active element, and each of the at least two passive antenna elements is individually set to a reflective or a transmissive mode to change the characteristics of an input/output beam pattern of the antenna apparatus.

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. A Multiple-Input, Multiple-Output (MIMO) processing technique may be employed to operate the antenna assembly with simultaneous beam patterns.

摘要： An adaptive antenna used in a receive only mode with a separate omnidirectional transmit antenna. The arrangement is especially effective for small, handheld wireless devices. The transmit antenna maybe integrated with the receive array by utilizing a horizontally polarized transmit and vertically polarized receiver ray. In other embodiments, the transmit antenna may be physically separate and not integrated with the receive array. In either case there is separate receive and transmit signal port as an interface to radio transceiver equipment. The use of an adaptive antenna in the receive only direction has the potential to increase forward links capacity to levels equal to or greater than reverse link capacity. This allows for a significant increase in the overall number of users that may be active at the same time in a wireless system.

摘要： A directional antenna having a number, N, of outlying monopole antenna elements. These monopole elements are formed as a first upper conductive segment on a portion of a dielectric substrate. The array also includes the same number, N, of image elements. The image elements are formed as a second set of lower conductive segments on the same substrate as the upper conductive segments. The image elements, generally having the same length and shape as the monopole elements, are connected to a ground reference potential. To complete the array, an active antenna element is also disposed on the same substrate, adjacent to at least one of the monopole elements. In a preferred arrangement, the passive monopole elements and corresponding image elements are selectively connected to operate to in either a reflective or directive mode, such as via a switchable coupling circuit that selectively changes the impedances connected between them.

摘要： A wideband circularly polarized antenna comprises a crossed-element spatial quadrature arrangement of log-periodic antenna elements. The orientation of one of the antenna arms of each diametrically opposed pair of arms is reversed from four port rose configuration, so that the antenna arms of each of the two pairs of elements have mutual mirror symmetry. As a result, each pair of antennal arms may be fed by phase quadrature ports of the same ninety degree hybrid, thereby significantly reducing the complexity of the feed network.

摘要： Electronic devices and antennas for electronic devices are provided. The antennas may have ground plane elements with dielectric-filled openings. The dielectric-filled openings may be configured to form one or more rectangular slots. The antennas may be fed using transmission lines having first and second conductors. The first conductor of a given transmission line may be coupled to the ground plane element on one side of the slots. The second conductor of the transmission line may be coupled to a planar conductive element. The planar conductive element may couple to the ground plane element on the other side of the slots. The slots may be separated by a portion of the ground plane element. The planar conductive element may bridge at least one of the slots and may overlap the portion of the ground plane element that separates the slots without electrically contacting that portion of the ground plane element.
