Passive device, it is widely used in the fields such as satellite communication, dual polarisation probe system, becomes in dual polarized antenna and feed
The important component of structure.Existing orthomode transducer is broadly divided into two kinds, and one is using ridge waveguide as Change-over knot
Structure, electric property is good, but since ridge waveguide tolerance is lower, processing technology is complicated and due to there is easy structure, ruler
It is very little larger；Another kind is the structure that coupling slot is opened using square wave guide, and both of which is transmitted separately in rectangular waveguide.This side
Case can effectively reduce the size of orthomode transducer, but due to it is compact-sized cause to be isolated between both of which it is poor.And show
Stage system is higher and higher to the insulated degree requirement between the volume and polarization of dual polarized antenna.Since the interference of some system counters has
Very high requirement, the polarization separation of current existing orthomode transducer are required from can no longer meet.
