    Abstract: A waveguide feed structure having a coaxial transmission line. A conductive, planar septum is disposed in, and along a diameter of, the transmission line. A feed port is electrically coupled to the transmission line. The septum has a rear portion disposed proximate the feed port, such rear portion of the septum extending between the inner conductor and the outer conductor. The feed port and the rear portion of the septum are arranged to establish an electric field in the transmission line between the inner conductor and the outer conductor with a component substantially TE11 mode along a direction perpendicular to the planar septum. A forward portion of the septum is asymmetrically disposed with respect to said diameter in order to provide a gap between the inner conductor and the outer conductor, such gap establishing an electric field component within the transmission line having a TE11 component along said diameter of the transmission line parallel to the plane of the septum. The septum has a pair of distal ends. One of the ends is separated from a proximate portion of the outer conductor has a distance different from the separation between the other one of the pair of ends and a proximate portion of the outer conductor. In one embodiment, the first-mentioned distance increases along the transmission line from the rear portion of the septum to the forward portion of the septum. The distance is increased in steps to provide a 90 degree phase shift to energy propagating along the transmission line between a distal end of the septum and the outer conductor.

    Abstract: A high-isolation polarization diverse circular waveguide orthomode feed apparatus capable of supporting any arbitrary linear, right-hand circular, left-hand circular or elliptically polarized electromagnetic wave with desirable performance over a broad range of frequencies and small size is disclosed. The waveguide feed employs the combination of a circular waveguide segment, stepped septum polarizer, and a novel arrangement of diametrically opposed electric field probes in the bifurcated region of the circular waveguide segment to achieve low crosspolarization when operating in arbitrary linear mode and high-isolation for rejection of undesired cross-polarization components when operating in circular or elliptical polarization mode. This apparatus is an elegant, simple, compact, rugged, and cost effective design that is applicable to a broad family of microwave antennas, but in particular those required to meet minimal radome swept volume requirements.

    Abstract: A pair of wave receiving probes is provided on opposite sides of an opening portion formed in a substrate. A waveguide is provided on one side of the substrate, and a wave reflecting unit is provided on the other side of the substrate. The wave reflecting unit is provided with a wave reflecting surface on an inner side of its end surface portion. A partition wall in a stepped pattern is provided in the waveguide, which penetrates the opening portion and extends to the end surface portion, thereby dividing the wave reflecting surface into two. The partition wall partitions the wave-guiding space formed by the waveguide, substrate and wave reflecting unit into two spaces. Accordingly, a polarized wave separator excellent in separating characteristics and preventing wave loss is realized.

    Abstract: The invention relates to an antenna source transmitting and receiving polarized microwaves, the source including a transducer for separating the transmission signals from the reception signals, the frequencies of the transmission signals being different from the frequencies of the reception signals. The connection between the transducer and the radiating element of the antenna is such that it maintains the polarization states of the signal received by the radiating element and of the signal transmitted to said radiating element. The transducer comprises a square-section waveguide, one end of which is connected to the radiating element, the other end being connected to the transmission path, the received signals being conveyed by the side faces of the waveguide. This source makes it possible to transmit and to receive in the enlarged C band, i.e. 3.4 GHz to 4.2 GHz on reception, and 5.85 GHz to 6.65 GHz on transmission.

    Abstract: A simple continuous metal pattern in a single plane is suspended in a waveguide filled with dielectric material. Two conductive pins penetrate the backshort of the waveguide in an axial direction and are connected at corresponding locations at opposite sides of the metal pattern. The metal pattern forms a radiating element in the shape of a continuous ring, having two convex (with reference to the central axis of the waveguide) primary antenna segments, each of which has one end joined to the corresponding end of the other segment by a narrow bridge segment. The opposite ends of the primary antenna segments extend generally away from each other and are joined by a narrow feedback segment. Within a desired frequency range of operation, the continuous metal pattern is excitable to produce both dominant orthogonal modes of circular polarization with the 90 degree phase difference and in both RHCP and LHCP orientation. More specifically, a modulated electrical signal supplied at one pin results in propagation of an RHCP signal from the waveguide, whereas a modulated electrical signal applied at the other pin results in propagation of an LHCP signal from the waveguide.
