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： An electronic device comprising a first conductive unit and a second conductive unit disposed such that a gap exists between the first component and the second component. The electronic device further includes one or more components disposed along the gap and configured to counteract one or more capacitance effects in the gap, wherein at least one of the first conductive unit and the second conductive unit represents a part of an antenna. By counteracting the capacitance effects in the gap, certain radiation attributes of the antenna, such as radiation efficiency, can be improved. The one or more components are also employed to counteract one or more capacitance effects in a slot of a conductive unit in an electronic device.

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.

摘要： A varactor based phase shifter that increases phase shift range using an impedance transformer to impart a low characteristic impedance between an input port and a reference node port. The characteristic impedance across the port is therefore less than the characteristic impedance would be otherwise, and the phase shift range is increased. In one embodiment, a simple reflection phase modifier can be used in a phased array using space feed parasitic antenna elements. This type of analog varactor reflection phase modifier can provide fine phase resolution, and the array can thus be used for low-loss adaptive beam forming.

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.
