Marconi antenna ________(a) is a grounded antenna(b) is an ungrounded

1.	Marconi antenna ________(a) is a grounded antenna(b) is an ungrounded antenna(c) can either be grounded or ungrounded antenna(d) can neither be grounded nor ungrounded antennaI got this question during an interview.I need to ask this question from Quadrature Carrier Multiplexing in chapter Double Sideband Suppressed Carrier Modulation of Analog Communications
Answer» Right answer is (a) is a grounded antenna For explanation I WOULD say: 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.
