A compact E-band (71–76 GHz) conductor-backed coplanar waveguide (CBCPW) to hollow metallic waveguide (WR-12) transition has been designed and fabricated. The fully-planar two-layer transition makes use of a double-slot antenna, which efficiently couples the millimeter-wave (mm-wave) signal from the CBCPW to the WR-12 waveguide. The introduced transition, together with an integrated high-speed balanced...
In this paper we present the design, construction and characterization of a broadband Orthomode Transducer (OMT) for the new Band 2+3 of the Atacama Large Millimeter/Submillimeter Array (ALMA). The term Band 2+3 (67–116 GHz) refers to the recent proposal of covering current Bands 2 and 3 with a single dual-polarization broadband receiver. One of the key components of the future receiver is the polarizer,...
