|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.
