摘要： There is disclosed an antenna apparatus used for satellite communication or the like and including an antenna rotating in an azimuth angle direction and an elevation angle direction, which can be miniaturized without using a slip ring for ensuring electrical connection between a stationary portion and a movable portion. A rotary member 3 is rotated by rotation of a motor 5 to rotate an antenna 11 about an azimuth axis. On the other hand, a motor 9 is rotated to rotate a rotary member 7, and a relative rotary shaft 14 is rotated by relative rotation between the rotary member 3 and the rotary member 7. The rotation of the relative rotary shaft 14 rotates the antenna 11 about an elevation angle axis by rotation transmission through a bevel gear 18 and a bevel gear 19.

摘要： A two-step method is used to reconfigure beams among different orbital slots for a satellite system. The satellite is biased at one or more orbital slots for a back-up mission, while it looks at the sub-satellite point for the primary mission. Body steering is achieved using pitch and roll biases. The main reflector of the antenna is gimballed in order to steer the beams to different locations for the back-up mission. Beam size is controlled through the use of different sized reflectors and by varying the feed size. Different sized beams are interleaved among multiple reflectors.

摘要： A full-wave loop antenna assembly having unique mechanical stability and electromagnetic characteristics is disclosed. The antenna assembly is suitable for use in the High frequency and Very high frequency portions of the electromagnetic spectrum and is capable of supporting multiple driven and parasitic elements in a variety of configurations for multi-band operation. The assembly includes an upper load-bearing boom and a lower boom which may be load bearing, between which at least a part of the weight loads created by the driven and parasitic elements may be distributed. The assembly may also include a parasitic element, tuned as a reflector, which is considerably longer than other parasitic reflectors which are used with antennas of this type, thereby providing the desired directional characteristics over a wider range of frequencies than are obtained by other antennas of its type.

摘要： A Radio Frequency (RF) microstrip antenna employs a planar or curved radiator element that is mounted or supported in spaced relation to a planar or curved ground plane element A RF feed is attached near one edge of the radiator element for receiving and/or transmitting RF signals; in a lobe that is substantially perpendicular to the ground plane element. The radiator element and the ground plane element are maintained in a converging inclined or tilted physical relationship. When a coaxial cable is employed as the antenna feed, the cable's outer insulation is secured to the ground plane element, the cable's center conductor extends away from the ground plane element to provide a signal feed to the radiator element and to provide physical support for one edge of the radiator element, and two insulator posts extend away from the ground plane element to provide support for the opposite edge of the radiator element. A two-piece, snap-together, radome is provided, wherein a bottom half nonmovably supports the feed line and ground plane member and adjustably supports the inclined radiating element, wherein a top half snap-fits to the bottom half and wherein the top half includes internal extenting tabs that engage edge portions of the ground plane member.

摘要： A suspension device for rotatable appliances, such as antennas, of the type which for rotation is connectible with a frame-mounted shaft which extends through a power operated disk or a similar antenna mounting and which, beyond the antenna mounting, has a free end mounted in a stationary part, which is capable of limited motion generated rated by insufficient concentricity between the antenna mounting and the shaft. An angle-transducing device is provided for said shaft. A connector is arranged adjacent to or round the shaft and directs components of force on the stationary part which have arisen owing to sufficient concentricity to merely displacement in the X-Y direction in a plane perpendicular to the shaft, by the connector being displaceably fixed in the X direction to the stationary part and displaceably fixed in the Y direction to the frame, or by the connector being displaceably fixed in the X direction to the shaft and displaceably fixed in the Y direction to the antenna mounting.

摘要： An RF beam pointing apparatus (500, 600) compensates for the effects of settling errors on antenna pointing. The beam pointing apparatus includes an attitude reference system (502, 528, 530, 534) generating an antenna attitude output from the satellite attitude. Also included is attitude comparison circuitry (528, 530), coupled to the attitude reference system, that includes an antenna pointing error output. Control circuitry (528, 530) is coupled to the attitude reference system (502, 528, 530, 534) and the attitude comparison circuitry (528, 530). The control circuitry (528,530) directs the attitude comparison circuitry (528, 530) to generate control error output signals in response to dynamic settling antenna pointing errors induced by a mechanical slew on the satellite. An electronic beam pointing system (500, 600) is provided to steer the antenna (544) in response to the antenna pointing error signals to reduce the dynamic settling antenna pointing errors to within a predetermined pointing accuracy for nominal operation (202).

摘要： A control status monitor/decision unit is added to a transmission power control apparatus which determines a transmission power level of a transmission signal to be output from an antenna via a transmission system and controls the same by referring to a received signal from the antenna obtained via a reception system. The unit monitors the control status in the control apparatus and performs the control of the optimum transmission power level according to this control status. By this, a further higher channel quality than that of the conventional apparatus can be maintained.
