摘要： A helical antenna element is made by stamping a helical antenna base shape from a sheet of metal and pressing a plurality of sub-elements within the helical antenna base shape to form a helical antenna element. The helical antenna base shape includes the plurality of sub-elements, a plurality of joining pieces and at least one carrier strip. The helical antenna element may be further made by molding an insulating resin around the helical antenna element. Moreover, prior to molding the insulating resin, a ceramic cylinder may be inserted within the helical antenna element to insure the integrity of the semi-circularly pressed sub-elements. The carrier strip(s) are then removed from the joint pieces, producing the helical antenna.

摘要： The present invention comprises a substantially omnidirectional antenna with minimal gain variation over the 360 degree azimuth. A plurality of biconical antenna elements are stacked, wherein a feed line passes through the center of the biconical antenna elements. The feed line is designed to provide the proper quantity of power to each biconical antenna element without the use of a power divider. Each biconical antenna element is formed by two truncated flared apart reflecting surfaces. Each biconical antenna element is attached to a nonconductive collar above and below.

摘要： A significant problem in rotationally symmetric dual reflector systems is the blockage caused by the sub-reflector. This blockage produces lower gain and higher side lobes. The invention disclosed herein can be used to minimize or eliminate the blockage effects. In its simplest form, the invention is to place a hole in the sub-reflector. This allows radiation to by-pass the main reflector and replaces the radiation which is blocked by the sub-reflector. In general this radiation and the radiation which progresses on the standard path, which includes the main reflector, will not be in a useful phase and amplitude relationship. However by appropriate design of the inner and outer sub-reflector surfaces, the main reflector surface, the feed aperture, the dielectric support and the possible use of a dielectric rod, the phase and amplitude relationships can be controlled. The invention also applies to cylindrical dual reflector systems which are symmetric about a plane.
摘要翻译：旋转对称双反射器系统中的一个重大问题是由副反射器引起的阻塞。这种堵塞产生较低的增益和更高的旁瓣。本文公开的本发明可用于最小化或消除堵塞效应。在其最简单的形式中，本发明是在子反射器中放置一个孔。这允许辐射绕过主反射器并且替换被子反射器阻挡的辐射。通常，这种辐射和在包括主反射器的标准路径上进行的辐射将不是有用的相位和幅度关系。然而，通过适当设计内部和外部副反射器表面，主反射器表面，馈电孔，电介质支架和可能使用介质棒，可以控制相位和幅度关系。本发明也适用于关于平面对称的圆柱形双重反射器系统。

摘要： A multi-band radial horn antenna is disclosed that has a precision 50 ohm feed line to ensure a match to a 50 ohm transmission line. The feed probe of the antenna has a threaded section that allows the antenna to be tuned quickly and precise in the field to provide maximum antenna performance. Once adjusted, a small locking nut is tightened to retain the physical location position. The antenna is economical to build as it has only four major parts. In operation, the antenna was found to have a 1.15 to 1 Standing Wave Ratio, a decade of frequency bandwidth and a low angle of radiation.

摘要： A dual band, higher and lower frequency range transducer with a circular coaxial waveguide feed is described having a first junction for connection of a lower frequency range outer waveguide of the coaxial waveguide feed to at least two rectangular or ridge waveguides offset from the longitudinal axis of the transducer and a second junction for connection of the at least two rectangular or ridge waveguides to a further waveguide. A third junction is provided for connecting an inner waveguide of the coaxial waveguide feed to a higher frequency range waveguide. The transducer comprises at least first and second parts joined across a first plane substantially perpendicular to the longitudinal axis and including at least a portion of the higher frequency range waveguide extending within the first plane of the join. A seal such as an nullOnull ring seal may be placed easily in the plane of the join thus preventing moisture ingress. Similarly, a feed horn and input and output ports may be sealingly attached to the first and second parts of the transducer. The first and second junctions are preferably impedance matched turnstile junctions.

摘要： An antenna system that employs antenna elements for both transmit and receive functions. Signals received by each antenna element are directed to a dual band polarizer that converts the signals to linearly polarized signals, and signals to be transmitted by each antenna element are converted to circularly polarized signals by the polarizer. The orientation of the polarizer and whether the circularly polarized signals are LHCP or RHCP determines whether the linearly polarized signals are vertically or horizontally polarized. A dual-band orthomode transducer is employed to separate the receive and transmit signals into their respective frequency bands based on whether they are vertically or horizontally polarized. The transducer is a waveguide device having only three signal ports. A high pass filter is used to help separate the received signals, and a low pass filter is used to help separate the transmit signals.

摘要： An antenna system that employs an antenna element for both transmit and receive functions, where a dual band polarizer is used to convert linearly polarized signals to circularly polarized signals and vice versa for two frequency bands. The dual band polarizer includes a waveguide including corrugated structures extending from opposing sidewalls, where ridges in the structures extend perpendicular to the propagation direction of the signal. The height of the ridges taper from a lowest height at the ends of the waveguide to a largest height at the middle of the waveguide. The corrugated structures interact with the field components of the signal in the direction perpendicular to the ridges that cause that component to be delayed relative to the field components parallel to the ridges so that the signal changes accordingly and maintains the same magnitude.

摘要： A primary radiator including a waveguide formed by winding a metallic plate into a cylindrical shape and superimposing both ends thereof at a joining portion. Two first flat portions and two second flat portions, extending in the direction of the central axis of the waveguide, are formed so that a first flat portion and a second flat portion alternate at intervals of substantially 90 degrees, thereby forming a total of four flat portions. A dielectric feeder includes a radiator section, an impedance converting section, and a phase converting section. By inserting the dielectric feeder into the inside portion of the waveguide, both side surfaces of the phase converting section are press-fitted/secured to the first flat portions, and both mounting surfaces at the outer peripheral surface of the impedance converting section are press-fitted/secured to the second flat portions, so that the phase converting section intersects at an angle of approximately 45 degrees a probe protruding from the phase converting section in the direction of the central axis of the waveguide.
