A type of radio antenna that includes a straight rod shape conductor that is perpendicularly mounted above a ground plane is known as a monopole antenna. This antenna is a simple and single-wire antenna, mainly used for both transmitting & receiving signals, so broadly used in wireless communication systems. Monopole Antenna.
A monopole antenna is one half of a dipole antenna, almost always mounted above some sort of ground plane. The case of a monopole antenna of length L mounted above an infinite ground plane is shown in Figure 1(a).
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.
Monopole Antenna is a kind of radio antenna that contains a straight rod-shaped conductor mounted above a ground plane. It includes a single wire that transmits and receives signals in numerous wireless communication systems. What is Monopole Antenna? Monopole Antenna was discovered in the year 1895 and radio expert Guglielmo Marconi.
The dipole and the monopole are arguably the two most widely used antennas across the UHF, VHF and lower-microwave bands. Arrays of dipoles are commonly used as base-station antennas in land-mobile systems. The monopole and its variations are common in portable equipment, such as cellular telephones, cordless telephones, automobiles, trains, etc.
A monopole antenna is half of a dipole antenna on top of a conducting ground plane. The most common type is a quarter-wave monopole where the antenna is approximately 1/4 of wavelength of radio waves. The radiation pattern is limited to above the ground plane of the antenna.
contrast to dipoles, which are symmetrical antennas, the nature of a monopole antenna is to be unsymmetric above earth. The monopole antenna measures the vertical polarized E-field
Monopole antennas, as shown in Figure 6.14, constitute a group of derivatives of dipole antennas. Here, only half of the dipole antenna is needed for operation. A metal ground plane (ideally of infinite size) is used, with respect to which the excitation voltage is applied to the half structure.
Module – 03 Lecture – 12 Monopole Antennas-II. Hello, and welcome to today’s lecture on Monopole Antennas. Now in the last lecture we discussed about various characteristics of monopole antenna.
combination of the two basic antennas: the monopole/dipole antenna and the biconical antenna. The discone and conical skirt monopoles find wide application in the VHF (30 to 300 MHz) and the UHF (300 MHz to 3 GHz) spectrum for FM broadcast, television and mobile communications.
