What is half wave length?
The length of the total wire, which is being used as a dipole, equals half of the wavelength (i.e., l = λ/2). Such an antenna is called as half-wave dipole antenna. This is the most widely used antenna because of its advantages. It is also known as Hertz antenna.
What is half wavelength dipole antenna?
The dipole antenna is cut and bent for effective radiation. The length of the total wire, which is being used as a dipole, equals half of the wavelength (i.e., l = λ/2). Such an antenna is called as a half-wave dipole antenna, also known as Hertz antenna.
What are the different types of monopole antenna?
Common types of monopole antenna are the whip, rubber ducky, helical, random wire, umbrella, inverted-L and T-antenna, inverted-F, folded unipole antenna, mast radiator, and ground plane antennas. The load impedance of the quarter-wave monopole is half that of the dipole antenna or 37.5 Ohms.
Does a half-wave antenna need a ground plane?
Does a 1/2 wave antenna need a ground plane? Answer: No. It does not require a ground plane to work efficiently. In fact it is best to install the 1/2 wave antenna at least 8 inches from any nearby metal objects for better performance.
What size should the half-wavelength dipole antenna be?
To make it crystal clear, if the antenna is to radiate at 600 MHz, what size should the half-wavelength dipole be? One wavelength at 600 MHz is = c / f = 0.5 meters. Hence, the half-wavelength dipole antenna’s length is 0.25 meters (or 9.85 inches if you don’t like the metric system).
What is half wave dipole theory?
Antenna Theory – Half-Wave Dipole. The dipole antenna is cut and bent for effective radiation. The length of the total wire, which is being used as a dipole, equals half of the wavelength (i.e., l = λ/2). Such an antenna is called as half-wave dipole antenna. This is the most widely used antenna because of its advantages.
Common types of monopole antenna are the whip, rubber ducky, helical, random wire, umbrella, inverted-L and T-antenna, inverted-F, folded unipole antenna, mast radiator, and ground plane antennas . The load impedance of the quarter-wave monopole is half that of the dipole antenna or 37.5+j21.25 ohms.
What is the load impedance of a quarter wave monopole antenna?
The load impedance of the quarter-wave monopole is half that of the dipole antenna or 37.5+j21.25 ohms.
