| dc.description.abstract | In this work we present a Q-band waveguide orthomode transducer (OMT) based
on a dual ridge structure. It was designed to be used in astronomical projects were an
excellent broad-band performance is mandatory. Of particular interest is the case of ALMA
Band 1 (originally set at 31-45 GHz) project which will need several OMTs with outstanding
performance and demonstrated manufacturability. By using a symmetrical structure, low
cross-polar level and good input matching are achieved over a broad bandwidth (37 %). The
proposed design incorporates an octagonal mode converter which allows the unit to be
directly mated with the horn avoiding cross-polar issues at the interface. The OMT was
designed to have a compact configuration and easiness of fabrication, both crucial features in
projects where several units (up to 70) have to be constructed. | |
