On the Performance Assessment Techniques of Orthomode Transducers
View through CrossRef
To assess the performance of orthomode transducers (OMTs), the
back-to-back (BTB) configuration is analyzed in simple fundamentals for
accurate results and clear physical insight. The axial rotation of an
OMT in the BTB measurement setup is investigated, and clear facts are
highlighted. Furthermore, terminating OMTâ\euro™s Common Port with a
short circuit load is proposed as a low-cost and accurate evaluation
technique based on detailed analysis. The presented techniques have the
advantage of using only power measurements without anechoic chambers. A
full-wave simulation of a published OMT operating at V-band (55 - 65)
GHz is used to validate these analyses.
