摘要： Steering of an electromagnetic beam of energy in the upper plate of a plate waveguide of a traveling wave antenna concurrently with the formation of a flat phase front and collimation of the electromagnetic beam is achieved by providing a second waveguide beneath the lower plate of the first waveguide and providing a 180% bend parabolic main reflector to reflect the energy beam to the upper plate of the upper waveguide. A feed horn is located in the lower waveguide and illuminates a pivotal subreflector which reflects the energy to the parabolic main reflector. By rotating the subreflector about its pivot point, the beam which is radiated to the upper waveguide is angularly shifted or steered.

摘要： A dual polarized, transmit/receive Cassegrain antenna system having an improved gain/temperature (G/T) ratio and improved effective isotropic radiated power (EIRP). The antenna has a main reflector, a subreflector, a waveguide feedhorn and a waveguide diplexernullortho-mode transducer (OMT) attached to the waveguide feedhorn at the vertex in the back of the main reflector. Vertical and horizontal components of the transmit and receive signals are separated into four independent channels. The four channels are coupled from the waveguide diplexer-OMT in four directions to allow placement of the vertical and horizontal solid state power amplifiers (SSPA) and the vertical and horizontal low noise amplifiers (LNA) directly on the back of the antenna. Location of the SSPAs and LNAs in this manner provides minimum transmission loss and volume.

摘要： When manufacturing waveguides, for example densely located waveguide channels, for electromagnetic waves such as microwaves, the channels are produced from rod-shaped bodies (1) of a material permeable to the waves and non significantly attenuating the waves. The bodies (1) can for example project from a base plate (3) and their side surfaces are coated with electrically conducting material but not their free end surfaces (5). The interior of the bodies form the waveguiding channels, which have their walls formed from the layer of electrically conducting material. By giving the rod-shaped bodies suitable shapes for example an antenna side or half of a waveguide antenna can be manufactured. The rod shaped bodies can before applying the electrically conducting material be coated with one or several layers of non-attenuating and non-conducting lacquer filling pores and smoothing the surface of the bodies. Thereby, the layer of electrically conducting material obtains a smooth transition surface to the material of the bodies giving the channels good waveguiding characteristics. If the material used in the bodies has a strong surface porosity, the channels formed from the rod-shaped bodies become strongly attenuating to the electromagnetic waves. A set of such bodies located at the sides of each other and having suitable dimensions of the bodies gives an element working strongly attenuating to the electromagnetic waves.
摘要翻译：当制造波导（例如密集定位的波导通道）用于诸如微波的电磁波时，通道可由波长可透过的材料的棒状体（1）产生，并且不会显着地衰减波。主体（1）可以例如从基板（3）突出，并且它们的侧表面涂覆有导电材料，而不是其自由端面（5）。主体的内部形成波导通道，它们的壁由导电材料层形成。通过给予棒状体适当的形状，例如可以制造天线侧或波导天线的一半。杆状体可以在施加导电材料之前涂覆一层或几层非衰减和非导电漆填充孔并使物体的表面平滑。因此，导电材料层获得平坦的过渡表面到达物体的材料，给出通道良好的波导特性。如果在体内使用的材料具有很强的表面孔隙率，则由棒状体形成的通道会强烈地衰减到电磁波。位于彼此侧面并且具有适当尺寸的这样的一组这样的主体给出了对电磁波强烈衰减的元件。

摘要： A flat plate or slab antenna (1) is fabricated from a number of sandwiched layers in which a number of arrayed individual antenna elements (3) are formed. The antenna elements (3) each include a horn (12) with a rectangular aperture (13) feeding (or fed by) individual rectangular waveguides (15). Two orthogonal probes (17,20) protrude into each waveguide (13), each of which is connected to respective beamforming networks. The network of first probes (17) operates at a first frequency while the network of second probes (20) operates at a frequency which is different from the first frequency. In the preferred embodiment, the edges (13) of the horn apertures (12) are parallel to the sides (6, 7, 8, 9) of the antenna slab while the walls of the rectangular waveguides are at 45null to the sides (6, 7, 8, 9) of the slab. The antenna (1) is able to receive and/or transmit two orthogonally linearly polarised signal at different frequencies and is therefore capable of full duplex operation. Various additional features are also described which reduce coupling between the first (17) and second (20) probes, improve isolation between receiving and transmitting sections and maximise power dissipation within the structure.

This dielectric leaky-wave antenna includes a ground plane, a dielectric slab which is laid on one surface of the ground plane and forms a transmission guide for transmitting an electromagnetic wave from one end side to the other end side between itself and the ground plane along the surface, perturbations which are loaded on the surface of the dielectric slab along the electromagnetic wave transmission direction of the transmission guide at predetermined intervals and leak the electromagnetic wave from the surface of the dielectric slab, and a feed which supplies the electromagnetic wave to one end side of the transmission guide.

摘要： A lens antenna including a lens body and/or a matching layer. In the lens antenna, lens body may be formed by a material containing thermoplastic elastomers. When a matching layer is formed on the surface of the lens body, at least one of the lens body and the matching layer is formed by a material containing thermoplastic elastomers. The use of thermoplastic elastomers in the lens body and/or the matching layer assist in reducing the formation of cracks therein.
