Dipole Antenna (Noun)
Meaning
An aerial half a wavelength long consisting of two rods connected to a transmission line at the center.
Classification
Nouns denoting man-made objects.
Examples
- A half-wave dipole antenna is often used for its simplicity and effectiveness in various radio communication systems.
- A common configuration for a television antenna is a dipole antenna with the rods oriented horizontally or vertically.
- The center of a dipole antenna is where the transmission line connects the two rods, feeding the signal into the antenna.
- A dipole antenna is often mounted high above the ground for horizontal polarization, allowing it to transmit radio waves over longer distances.
- The length of a dipole antenna is typically half the wavelength of the frequency being transmitted, making it an efficient radiator.
