Waveguide to Coaxial Adapter

As we know waveguide adapter is a device which provides interface between two different transmission lines so that Electro-magnetic waves having different modes in them can be coupled from one line to the other and vice versa.

Microstrip circuits are very popular for RF circuit designs at higher frequencies. Sometimes it is required to feed higher power at these frequencies. This can not be done using coaxial line. Hence the same is done by using Waveguide Adapter which will interface waveguide with the microstrip circuits in different ways. It takes care of EM wave mode conversions between microstrip and waveguide.
