Abstract

We present simulations and discuss measurements of a planar orthomode transducer (OMT) being developed for use with bolometric detectors in observations of the polarization of the cosmic microwave background (CMB). This OMT couples radiation from a circular waveguide onto microstrip where it is filtered and then detected. A corrugated feed horn defines the optical beam. Simulations suggest this OMT achieves a coupling efficiency of greater than 96% with crosspolarization below 1% over 30% bandwidth.
