Abstract: Disclosed is an electronic device having wireless communication functions via a pair of antennas. The device can function under two operating states, both with an omni-directional radiation pattern in the horizontal plane. This is accomplished by an antenna pair mounted separately thereon, the first antenna thereof being omni-directional in the horizontal plane when the device is operative under the first operating state, and the second antenna thereof being omni-directional in the horizontal plane when the device is operative under the second operating state.

Abstract: An integrated dual-directional feed horn, for receiving RF signals from two satellites in small angle, includes a LNBF (first low noise block with integrated feed) and a second LNBF. The antenna dish focus the received RF signals onto receipt points of the focus plane, and the two LNBFs receive focused RF signals. The first LNBF receives circular polarized waves from the BSS satellite. The second LNBF receives linear polarized waves from the FSS satellite. One characteristic of the invention relies on integrating two LNBFs and making the two LNBFs adjacent to each other in the direction of short axis. Accordingly, the two LNBFs receive RF signals from two satellites in small angle. Increasing the length of the long axis thereof increases the areas of the wave-guides. The signal gain and communication quality are obtained.

Abstract: The object of the present invention is to provide an antenna pair that has the advantages of easy installation and improved gain. According to the present invention, the antenna pair consists of two slot antennas formed on a metallic strip and sharing a common portion of the strip as the grounding unit. The grounding portions of the antennas join together to become the grounding unit so as to increase the effective antenna aperture for both of the antennas and to raise their gains. As the antennas are combined into one, it is more manageable and handy for installation. The grounding unit can be further extended to allow greater improvement. The strip on which the slot antennas are formed is curved to have the antennas orthogonal to each other. The orthogonality brings about the space diversity effect and prevents the occurrence of any null in the radiation pattern of the antennas.

Abstract: A laptop computer with an embedded antenna is disclosed. The laptop computer contains an LCD panel and an antenna embedded inside the LCD panel. The antenna is embedded in the gap between the covering of the LCD panel and the frame supporting the LCD on the LCD panel. The ground surface of the antenna is effectively extended through incorporating the conducting surface on the back of the LCD. When the LCD panel is opened the antenna is at a distance above the operating surface of the laptop computer and produces omni-directional radiation pattern in the horizontal plane.

Abstract: A rotation apparatus for a dish antenna provides a system for easily adjusting the dish antenna to a precise receiving position. The rotation apparatus includes a dish bracket which is fixed to the back of the dish antenna. The dish bracket includes a plurality of circular grooves and a concentric axle center. An elevation bracket includes a pair of wings and a bottom. The wings are parallel, and the bottom is perpendicular to the wings. Each wing pivots about an axle which passes through a first portion of each wing. A second portion of each wing includes a guide groove to adjust a elevation angle of the dish. The bottom includes a central axle hole and a plurality of holes. The central axle hole is coupled to the concentric axle center. After the dish is rotated to a selected position, the plurality of holes are secured to the circular grooves using a plurality of screws.

Abstract: An antenna apparatus for providing wireless communication comprise a first antenna plate, a second antenna plate and a matched circuit. The matched circuit has a front line and a transferring line so as to be formed as an appropriate impedance between the first antenna plate and the second antenna plate, wherein one end of the transferring line is coupled to the front line forming a T shaped converging portion having a first feedback point and a second feedback point. The first antenna plate has an electrical foot connecting to the first feedback point and a ground foot connecting to the ground. Similarly, the second antenna plate has an electrical foot connecting to the second feedback point and a ground foot connecting to the ground.

Abstract: This invention relates to an antenna for a portable device. The portable device comprises a display, a host. In addition, a hinge is provided to connect the display and the host such that the display can be rotated relative to the host. Therefore, the portable device can be opened and closed accordingly. Furthermore, a receiver is installed within the hinge so that an antenna can be fixed in the hinge. Thereby, wireless transmitting of the portable device can be achieved through the antenna.

Abstract: This invention is a compact and cost effective signal receiver for use in conjunction with a parabolic reflector to receive electromagnetic signals from two satellites. The signal receiver has a dual elliptical corrugated feed horn to increase C/N ratio and reduce the spill over loss of the energy of signals receiving from two satellites, and to provide a sufficient rejection for preventing interference coming from the other satellite.

Abstract: This invention discloses a novel design for receiving electromagnetic signals broadcasted from at least two of satellite clusters and collected by a single dish antenna. At least two signal feeds are used to feed the signals to a processing circuit. The processing circuit performs signal selection, amplification, and frequency conversion. Corrective lens are used to ensure uniform wavefront of the electromagnetic signals received by the signal feeds located farther away from the focal point of the dish antenna. A convenient adjustment device is provided for adjustment of the relative positions of the signals feeds to the dish antenna.
