| Waveguide | Transmission Line |
|---|---|
| The waveguide is a hollow metallic structure through which electric and magnetic fields are transmitted. | The transmission line is a conductor which is used to carry electrical signal over a long range. |
| It has simple to manufactured. | It has complex to manufactured. |
| In waveguide the power handling is high as compared to transmission line. | In transmission line the power handling is low as compared to waveguide. |
| The Operating modes are TE or TM mode. | The operating mode are TEM or quasi TEM mode. |
| In waveguide high power is transmitted. | In transmission line low power is transmitted. |
| In waveguide the electromagnetic signal is transmitted. | In transmission line the electrical signal is transmitted. |
| The operating frequency is 3 GHZ to 100 GHZ in waveguide. | The operating frequency is up to 18 GHz. |
