Advantages:
The circular waveguide are easier to manufacture than rectangular waveguides and are easier to join.
The TM01 modes are rotationally symmetrical and hence rotation of polarization can be overcome.
TE01 mode in circular for long distance waveguide transmission.
Applications:
Rotating joints in radars to connect the horn antenna feeding a paraboloid reflector (which must rotate for tracking).
TE01 mode is suitable for long distance waveguide transmission above 10GHz.
Short and medium distance broad band communication (cold replace/share coaxial and microwave links).
It is used where the transmission or reception is in the range of microwave frequencies.
It is also used for handling the high power of energy. It is mostly used in the airborne radar.
