The shape of the radiating ... A monopole antenna is a class of radio antenna consisting of a straight rod-shaped conductor, often mounted perpendicularly over some type of conductive surface, called a ground plane. The driving signal from the transmitter is applied, or for receiving antennas the output signal to the receiver is taken, … Prikaži več The monopole antenna was invented in 1895 and patented in 1896 by radio pioneer Guglielmo Marconi during his historic first experiments in radio communication. He began by using dipole antennas invented … Prikaži več Because it radiates only into the space above the ground plane, or half the space of a dipole antenna, a monopole antenna over a perfectly conducting infinite ground plane will have a gain of twice (3 dB greater than) the gain of a similar dipole antenna, and a Prikaži več • "Radiation of a quarter wavelength monopole". Prikaži več Like a vertically suspended dipole antenna, a monopole has an omnidirectional radiation pattern: It radiates with equal power in all Prikaži več For monopole antennas operating at lower frequencies, below 20 MHz, the ground plane is usually the Earth; in this case the antenna is a vertical mast mounted on the ground on an … Prikaži več • Antenna types • Cellular repeater • Dual-band blade antenna • Electrical lengthening Prikaži več
