The invention publishes a wave guide array antennas manufacture method of high gain crewel polarized or the double circular polarized, which relates to a wave guide array antennas manufacture technique in the correspondence broadcast and measure-control domain. The invention has designed the radiation level, the horizontal polarization or the circular polarization feed wave guide level, the perpendicular polarization feed wave guide level, the perpendicular polarization feed wave guide lap, the feed way of using the square or the circular waveguide resonant cavity, has solved the receive and launch of the double polarized electromagnetism signal; The horizontal polarization uses the coupling feed way and the perpendicular polarization uses the direct feed way, completes the separation of the two polarized components, simultaneously may realizes the double circular polarized work. The invention has the double polarized radiation, the high feed efficiency, compact structure, low processing cost and so on merits, is specially suitable for the manufacture of each kind of satellite communication or single control station antenna which works in the double thread polarization or double circular polarized application situations.

The invention discloses a non-array aperture antenna wave beam tilt electronic antenna and an implementation method thereof. The non-array aperture antenna wave beam tilt electronic antenna comprises an aperture antenna and a control antenna. Electric field distribution in a feed source loudspeaker aperture face is changed through an assembly structure and an excitation element antenna used for producing a tilt wave beam, aperture face antenna main wave beam tilt is achieved, and scanning of a wave beam in space is formed through a periodic excitation patch antenna. The aperture antenna is a feedforward reflector antenna. The control antenna comprises an interference antenna, a fixing ring, a fixing base and a compression plate. The polarization mode of the control antennal includes but not limited to linear polarization, dual linear polarization, circular polarization and dual circular polarization. The defects in the prior are overcome, antenna units do not need to be arrayed according to the method, and the non-array aperture antenna wave beam tilt electronic antenna has the advantages of being simple in structure, easy to implement and convenient to control.

The invention discloses a common-caliber multiplexing multi-band full-polarization antenna feed source device. A quadruple-ridged horn and a square waveguide are adopted, so that the common-caliber multiplexing multi-band full-polarization antenna feed source device can simultaneously work on an X band, a Ka band and a Ku band for carrying out signal transmitting and receiving work through improvement of the structure of the quadruple-ridged horn and the square waveguide. Furthermore, the quadruple-ridged horn is adopted, so that the dual-linear polarization requirements are achieved. The square waveguide can be adopted as multiple channels to achieve a monopulse radar.
