摘要： Disclosed is a waveguide adapter able to generate a circularly polarized wave. The waveguide adapter to be coupled with a horn antenna realizes a polarized wave conversion function for converting a linearly polarized wave signal into a circularly polarized wave signal, or vice versa, and an adapter function for converting a waveguide signal into an external transmission line signal, resulting in a simplified configuration and small size of a communication system using a circularly polarized wave signal. The waveguide adaptor includes a probe to transmit a linearly polarized wave signal from an external transmission line to a waveguide transmission line, a polarized wave conversion line reflector located in the rear of the probe to convert a vertically polarized wave into a horizontally polarized wave, and a back-short member to forwardly transmit a rearward signal. The waveguide adapter is applicable to communication systems using circularly polarized wave signals.

摘要： An object is to provide for receiving a circularly polarized signal from an antenna feed (10) connected to orthogonally spaced antenna elements (11, 12, 13, 14) and for transmitting a linearly polarized signal through the same feed without switches, and without suffering a 3 dB polarization mismatch loss, using an arrangement of hybrid junctions. The arrangement is comprised of two dividing hybrid junctions (15, 16), each connected to a different pair of antenna elements and a summing hybrid junction (17). In one embodiment, a receiver (18) is connected to the summing hybrid junction directly. A diplexer (19a or 19b) is used to connect a transmitter (20a or 20b) to only one pair of antenna elements. In an alternative embodiment, designated left and right circularly polarized (LCP and RCP) transmitters (21, 22) are connected to the summing hybrid junction by separate diplexers (23, 24), and separate LCP and RCP sensitive receivers (25, 26) are connected to the diplexers in order to transmit linearly polarized signals using all four antenna elements while receiving circularly polarized signals as before. An orthomode junction (30) and horn antenna (32) may replace the two dividing hybrid junctions (15, 16) and antenna feed (10).

摘要： A single in-plane orthogonal mode launcher for generating circularly polarized waves having both right and left hand senses is disclosed. A 90.degree. hybrid provides first and second signals to respective input ports of the launcher. First and second coplanar sets of probes are orthogonally disposed in a cylindrical housing and connected to the first and second ports, respectively. The first set of probes generates a first vector signal. The second set of probes generates a second vector signal which is 90.degree. to the first vector signal. Since the input signals to the first and second sets of probes are 90.degree. out of phase, circularly polarized waves are thus generated.
