A Marconi antenna has length equal to ________(a) ^ʎ⁄4(b) ^ʎ⁄2(c) 1(d) ^ʎ⁄8I had been asked this question in an online quiz.The question is from Problems of DSBSC in portion Double Sideband Suppressed Carrier Modulation of Analog Communications

Answer»

The correct option is (a) ^ʎ⁄4

To elaborate: MARCONI antenna is like a vertical wire having length one fourth of the working wavelength. Thus, it is a quarter-wave monopole antenna. SINCE, it was INVENTED by Guglielmo Marconi, so it’s also called Marconi Antenna. It requires a ground plane with very GOOD conductivity. Hence it is also called as a grounded antenna.
