A reflector antenna system having a diplexer for providing isolation between transmitted and received signals, which eliminates the need for a diplexer to be inserted into the waveguide or coax transmission line coupling the antenna system with an external antenna electronics subsystem. The antenna system includes a main reflector to which is coupled a low effective dielectric tube. Transmit and receive feedhorns are supported within the tube. A hyperboloidal receive bandpass filter is supported in front of the receive feedhorn and a hyperboloidal transmit bandpass filter is disposed in front of the transmit feedhorn. The receive bandpass filter allows the received signal to pass therethrough but blocks the transmitted signal from the transmit feedhorn. Conversely, the transmit bandpass filter reflects the received signal received from the subreflector surface back towards the receive feedhorn while allowing the transmitted signal from the transmit feedhorn to pass therethrough.

An improved method is provided for pointing an antenna subsystem residing on a mobile platform towards a satellite in a satellite communication system. The improved method includes: transmitting a tone signal from the satellite; receiving the tone signal at the antenna subsystem; determining position of the mobile platform in relation to the satellite a monopulse tracking technique, where the position of the satellite is based on the tone signal received at the antenna subsystem; and pointing the antenna subsystem towards the satellite.

A microwave reflector antenna comprises a rotary plate that rotates about an azimuth axis. At least one elevation cradle is attached to the rotary plate to provide an elevation axis and rotates about the azimuth axis with the rotation of the rotary plate. The at least one elevation cradle has a curved guide with a plurality of ball bearings to facilitate the rotation of the reflector about the elevation axis. A reflector travels along the at least one cradle as the reflector rotates about the elevation axis. The reflector rotates about the azimuth axis with the rotation of the at least one cradle. The rotation of the reflector about the azimuth axis and about the elevation axis define a swept volume of the reflector. The at least one cradle is positioned on the rotary plate so that the at least one cradle is within the swept volume of the reflector.

H01Q 128

343705, 343708

A reflector for use under a radome disposed on a mobile platform such as an aircraft for reflecting a portion of the electromagnetic energy radiated by an antenna disposed under the radome such that the reflected portion of energy impinges the radome at an angle normal thereto, thereby reducing or eliminating further reflections of the reflected portion of energy within the radome toward the mobile platform on which the radome is mounted. In one preferred embodiment the radome includes a base portion which is covered with a cover of radar absorbing material (RAM). In another embodiment the radome includes a curved base portion which is adapted to match the curvature of the surface of the mobile platform on which the reflector is mounted.

A microwave reflector antenna for use on an aircraft. The microwave reflector antenna has a stationary plate that is attached to and stationary relative to the aircraft. A rotary plate rotates relative to the stationary plate about an azimuth axis. A rotary joint is attached to the rotary plate and has an axis of rotation that is aligned with the azimuth axis. A reflector is attached to the rotary plate adjacent the rotary joint so that the azimuth axis does not intersect the reflector. Individual ball bearings are positioned between the rotary plate and the stationary plate to allow the rotary plate to rotate about the azimuth axis. The stationary plate has gear teeth positioned along a peripheral side wall of the stationary plate. An azimuth motor is attached to the rotary plate and engaged with the gear teeth to selectively rotate the rotary plate about the azimuth axis.

A microwave antenna for an aircraft including a reflector element with a front surface and a rear surface. A horn is mounted to the front surface of the reflector element and an orthomode transducer is mounted to the rear surface of the reflector element. The orthomode transducer is coupled to the horn. Solid state power amplifiers that amplify a microwave signal to be transmitted and low noise amplifiers that amplify a received microwave signal are coupled to the orthomode transducer. The solid state amplifiers and the low noise amplifiers are also located on the rear surface of the reflector element.

A multi-reflector antenna array capable of simultaneously transmitting and receiving communication signals at Ku-band frequencies is mounted on an exterior surface of an aircraft. The antenna array provides four cassegrain reflector antennas mechanically connected together in a group capable of being simultaneously mechanically scanned. A common support structure fixes the antennas with respect to each other. A drive mechanism and directional azimuth and elevation motors control the position of the array. The aerodynamic drag of the array is minimized using four antennas rather than a single large diameter antenna. Each antenna is positioned on a common horizontal centerline. Two centrally located antennas are positioned between two smaller diameter antennas. The antennas and positioning equipment are both mounted for rotation within a radome. A corporate power combiner/divider is provided to adjust both an amplitude and a phase of each antenna signal.

An antenna system includes a feedhorn, main reflector, sub-reflector, and frequency selective member. The sub-reflector includes an axially symmetrical reflecting surface. The frequency selective member includes an axially non-symmetrical reflecting surface. The frequency selective member transmits signals having a first frequency from the feedhorn to the sub-reflector. These signals are symmetrically reflected by the sub-reflector to the main reflector. The frequency selective member reflects signals having a second frequency from the main reflector to the feedhorn. These signals are reflected at a small conical angle by the frequency selective member to the feedhorn. In this way, the present transmit/receive system provides coincident transmit and receive signals with only conically scanned receive signals.
