20090153409 | MICROSTRIP ANTENNAS FOR ELECTRONIC DEVICES - Microslot antennas may be provided for electronic devices such as portable electronic devices. The microslot antennas may have dielectric-filled microslots that are formed in a ground plane element. The ground plane element may be formed from part of a conductive device housing. The microslots may be narrow enough that they are not readily noticeable to the naked eye. The microslots may have lengths that allow the microslot antenna to provide antenna coverage in one or more communications bands. A first group of the microslots may be used to provide coverage in a first communications band and a second group of the microslots may be used to provide coverage in a second communications band. | 06-18-2009 |
20090153411 | DUAL-BAND ANTENNA WITH ANGLED SLOT FOR PORTABLE ELECTRONIC DEVICES - Dual slot antennas are provided for portable electronic devices such as handheld electronic devices. A dual slot antenna may have an open slot that has an open end that is not encircled by conductive material and may have a closed slot in which each end is surrounded by conductor. The closed and open slots may have portions that run parallel to each other. The antenna may be fed using feed terminals that bridge the closed and open slots in the vicinity of the portions of the slots that run parallel to each other. The slots may have portions that are angled with respect to each other. An end portion of one of the slots may be bent and widened for impedance matching and broadened bandwidth. Other portions of the slots may also be angled with respect to their main longitudinal axes. | 06-18-2009 |
20090153412 | ANTENNA SLOT WINDOWS FOR ELECTRONIC DEVICE - 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. | 06-18-2009 |
20090153422 | ANTENNAS WITH PERIODIC SHUNT INDUCTORS - 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. | 06-18-2009 |
20090174612 | ANTENNAS AND ANTENNA CARRIER STRUCTURES FOR ELECTRONIC DEVICES - Antenna support structures and antennas are provided for wireless electronic devices such as portable electronic devices. Antenna resonating elements may be formed from conductive coatings on two-shot molded interconnect device dielectric antenna support structures. The conductive coatings may be formed from wet-plated copper or other conductive materials. The antenna support structure may have tabs that electrically connect antenna resonating elements to the case of a wireless electronic device that serves as an antenna ground plane. The antenna support structure may be curved about its longitudinal axis so that the antenna resonating elements on the support structure protrude upwards to enhance antenna performance. In a portable electronic device such as a portable computer, the antenna support structure may be mounted within a dielectric portion of the computer housing that is located between the display portion of the housing and the base of the housing. | 07-09-2009 |

20110169700 | ANTENNAS FOR ELECTRONIC DEVICES - A removable antenna and a resilient antenna are provided for an electronic device such as a laptop computer. An antenna resonating element is mounted within the antenna. Flexible coupling structures are used to physically and removably attach the antenna to the electronic device. The flexible coupling structures couple the antenna resonating element to circuitry in the electronic device. The coupling structures may allow the antenna to break away from the electronic device without causing damage. A user may extend the antenna by rotating the removable antenna to its extended position. The electronic device may have an antenna receptacle that holds the resilient antenna in a stowed position and that allows the resilient antenna to flex to an extended position. A user may extend the resilient antenna by removing the resilient antenna from the antenna receptacle and flexing the antenna into its extended position. | 07-14-2011 |
20120001825 | METHODS AND APPARATUS FOR IMPROVING THE PERFORMANCE OF AN ELECTRONIC DEVICE HAVING ONE OR MORE ANTENNAS - 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. | 01-05-2012 |
