    摘要： The present microwave transmit/receive antenna feed of a microwave communication system for transmitting and/or receiving orthogonal components of a linearly polarized microwave radio signal, enabling reception in one or two frequency ranges, reception and transmission in two frequency ranges, or transmission in one or two frequency ranges, has a waveguide of a circular or rectangular cross-section and is characterized in that there is at least one plane with a recess (6) fashioned on the lateral side of the body (5) of the feed (1), into which recess (6) at least one electronic circuitry (14) is placed and fixed. There is at least one bore through the plane into the waveguide (10, 11), wherein a probe (12, 13) is inserted, protruding into the waveguide (10, 11) and outwards, and is electrically and mechanically coupled to the electronic circuitry (14). The configuration according to the invention allows antenna feeds of exceptional compactness, reliability and simplicity to be manufactured.

    摘要： The invention proposes an LNB using two transposition frequencies chosen on either side of the reception band 200 so as to obtain a transposition of supradyne type 205 and a transposition of infradyne type 204 according to the frequency used. This choice of transposition frequencies makes it possible to have an overlap zone 202 in the middle of the reception band which is transposed with the aid of the two oscillation frequencies but at different frequencies. This makes it possible to choose between the two transpositions in the case where the frequency transposed with the aid of an oscillator corresponds to a particularly noisy frequency.

    摘要： The present invention relates to antenna feeds (10, 30, 70, 78, 94) for use in linear or circularly polarised systems. In one embodiment of the invention, a cross-type antenna feed (30) comprises a cylindrical metal waveguide housing (12) and a cross-type metal feed body (32) coupled to the front of the waveguide housing (12). The feed body (32) has four peripherally spaced corrugated arm portions (34) arranged in a mutually orthogonal relationship, where the arm portions (34) extend radially outwardly from a longitudinal axis (16) of the feed body (32). Ridges (36) on each arm portion (34) are arranged concentrically around the axis (16) and parallel thereto, with successive ridges spaced from the axis (16) in a tiered arrangement. In another embodiment the antenna feed is a dielectric lens. The antenna feed is used in an antenna system having a reflector antenna in addition or in a low noise block (LNB) receiver.
