摘要： Antennas for electronic devices are provided. First and second antennas may be mounted within an electronic device. Free-space coupling between the first and second antennas may give rise to interference. The first and second antennas may be coupled to a global ground. The global ground may be formed using a conductive member in the electronic device such as a conductive frame member. Signals that pass between the antennas through the global ground may serve as canceling signals that reduce the magnitude of free-space interference signals and thereby improve antenna isolation. The antennas may be coupled to the global ground using electrical paths or through near-field electromagnetic coupling. Coupling efficiency to the global ground may be enhanced by configuring the conductive traces of one or both of the antennas to form a resonant circuit.

摘要： An antenna may be formed from conductive regions that define a gap that is bridged by shunt inductors. The inductors may have equal inductances and may be located equidistant from each other to form a scatter-type antenna structure. The inductors may also have unequal inductances and may be located along the length of the gap with unequal inductor-to-inductor spacings, thereby creating a decreasing shunt inductance at increasing distances from a feed for the antenna. This type of antenna structure functions as a horn-type antenna. One or more scatter-type antenna structures may be cascaded to form a multiband antenna. Antenna gaps may be formed in conductive device housings.

摘要： Antenna window structures and antennas for electronic devices such as portable electronic devices are provided. The electronic devices may be computers or other devices that have conductive housings. Antenna windows may be formed from one or more slots in the conductive housings. The slots may be filled with air or a solid dielectric such as epoxy. There may be a number of parallel slots in a given antenna window, each having a width that is sufficiently narrow to make the antenna window invisible or unnoticeable to the naked eye under normal observation. An antenna may be formed within an electronic device adjacent to an antenna window. The antenna may handle radio-frequency antenna signals in one or more communications bands. The radio-frequency antenna signals may pass through the slots in the antenna window.

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 includes a ground plane and an active antenna element adjacent the ground plane. Passive antenna elements are adjacent the ground plane, and are spaced apart from the active antenna element. First parasitic gratings are adjacent the ground plane and are spaced apart from the active antenna element. Each first parasitic grating is between two adjacent passive antenna elements. A controller selectably controls the passive antenna elements for operating in a reflective mode or a directive mode. The controller includes for each respective passive antenna element at least one impedance element connected to the ground plane, and a switch adjacent the ground plane for connecting the at least one impedance element to the passive antenna element so that the passive antenna element operates in the reflective or directive mode.

摘要： An active antenna element to transmit and/or receive RF (Radio Frequency) signals is positioned in relation to a backplane that reflects RF signals. One or more passive antenna elements can be disposed on a similar side of the backplane as the active antenna element. Settings of the one or more passive antenna elements are adjusted to produce an input/output beam pattern that varies depending on whether the at least one passive antenna element is reflective or transmissive. Based on this technique, an RF input output beam pattern of an antenna assembly including the backplane, active antenna element and passive antenna elements can be controlled for better reception and transmission of RF signals.

摘要： A varactor based phase shifter that increases phase shift range using a lower characteristic impedance between quadrature ports than is used at its input/output ports. The circuit makes use of a four port coupler arrangement that imbeds a quarter wave impedance transformation between the input port and the quadrature ports as well as between the quadrature ports and the output port. The characteristic impedance across the quadrature ports is therefore less than the characteristic impedance across the input and output ports. In one implementation, reducing a characteristic input/output impedance of 50 to a 20 ohm quadrature port impedance results in a phase shift range increase of more than 50%.
