A cantenna (a portmanteau blending the words can and antenna) is a homemade directional waveguide antenna, made out of an open-ended metal can. Cantennas are typically used to increase the range (or discovery) of Wi-Fi networks.
A television antenna, also called a television aerial (in British English), is an antenna specifically designed for use with a television receiver (TV) to receive terrestrial over-the-air (OTA) broadcast television signals from a television station.
History [ edit ] Arnold B. Bailey was granted the US patent 2,184,729 Antenna System on December 26, 1939, after filing in 1937 for a vertical antenna providing coaxial element sleeve structures.
Gannicus and Castus met their end at the Battle of Cantenna in Lucania near Mount Soprano (Mount Camalatrum), where Marcus Licinius Crassus, Lucius Pomptinus and Quintus Marcius Rufus entrenched their forces in battle and defeated them.
The waves travel down a horn as spherical wavefronts, with their origin at the apex of the horn, a point called the phase center. The pattern of electric and magnetic fields at the aperture plane at the mouth of the horn, which determines the radiation pattern, is a scaled-up reproduction of the fields in the waveguide.
In radio communication, an omnidirectional antenna is a class of antenna which radiates equal radio power in all directions perpendicular to an axis (azimuthal directions), with power varying with angle to the axis (elevation angle), declining to zero on the axis.
Antenna (radio), also known as an aerial, a transducer designed to transmit or receive electromagnetic (e.g., TV or radio) waves Antenna types, a list of the many different types of radio and microwave antennas
Types of parabolic antennas Corner reflector part of a UHF television antenna. The function of a standalone reflector is to redirect electromagnetic (EM) energy, generally in the radio wavelength range of the electromagnetic spectrum.
