Symmetric orthomode coupler for cellular application |
摘要 |
An orthomode coupler (10) for directing both satellite uplink and downlink signals. The coupler (10) includes a waveguide structure (14) having a first cylindrical section (28), a conical section (30) and a second cylindrical section (34) providing a waveguide chamber (22) therein. The conical section (30) provides impedance matching of the downlink signal between the waveguide structure (14) and a plurality of symmetrically disposed downlink waveguides (38-44). The waveguides (38-44) are positioned around the waveguide structure (14) and are in signal communication with the waveguide chamber (22) through openings in the tapered section (30). Irises (46-52) are provided at the connection between the downlink waveguides (38-44) and the waveguide chamber (22) for impedance matching purposes.
