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.
