    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.

    摘要： A radio transmitter for transmitting signals in a predetermined frequency band has a transmit filter (36) and a compensating filter (48). The transmit filter (36) filters a signal to be transmitted from the transmitter to suppress the transmission of parts of the signal outside the band. The compensating filter (48), e.g., operating in the digital domain, filters the signal upstream from the transmit filter, wherein the compensating filter is arranged to alter the signal to counteract at least one of a phase ripple, an amplitude ripple, and a group delay variation of the transmit filter within the band.

    摘要： A line hanger (10) for securing lines, such as transmission, pneumatic, hydraulic, electrical and other types of lines, to a support structure and a method of mounting and supporting one or more lines from a support structure. The line hanger includes an attachment support provision (14) configured for mounting to the support structure and a pair of spaced-apart clamping arms (16,18) depending outwardly from the attachment provision (14). The clamping arms (16,18) are configured to resiliently separate for slidingly receiving a line and to resiliently relax for applying a clamping force to secure the line. Multiple line hangers (10) may be interlinked or stacked relative to the support structure for support multiple lines.
