| Sr No. | Waveguide | Two wire Transmission line |
|---|---|---|
| 1 | A waveguide is a hollow metallic pipe design to carry microwave energy from one place to another | Transmission on line is a conductor or wire designed to carry electrical energy below microwave range from one place to another |
| 2 | Used for Microwave frequency above 1GHz | Used for RF up to 500 in GHz. Upto 18 GHz For short distance. |
| 3 | Power handling capacity is high | Power handling capacity is low |
| 4 | Wave theory is considered in waveguide analysis | Circuit theory considered in Transmission line |
| 5 | The large surface area of waveguide reduces copper losses | Two wire transmission line have large copper losses due to small surface area |
| 6 | Dielectric losses are less in waveguide | Dielectric losses are more in Two wire Transmission line |
| 7 | It acts as a High Pass Filter | All frequencies can pass through |
| 8 | TE and TM modes exist in WG. | TEM mode exists in TL. |
| 9 | Wave impedance (characteristic impedance) is a function of frequency. | Characteristic impedance in TL depends on the physical parameters of TL. |
| 10 | It is one conductor transmission system. The whole body of the waveguide acts as ground. The wave propagates through multiple reflections from the walls of waveguide (WG). | It consists of two conductors. One or both conductors are used to carry the wave. |
