Television antenna - Wikipedia

Television antenna - Wikipedia The boundaries of each band vary somewhat in different countries. Some older television stations broadcast in horizontal polarization which requires that the antenna elements be horizontal, but most broadcast in circular polarization, so that linearly polarized antennas can receive the signal equally well in any orientation. POLARIZATION SWITCHING/VARIABLE DIRECTIVITY ANTENNA - US ... A polarization switching/variable directivity antenna according to the present invention includes a ground conductor plate 12 on a surface of a dielectric substrate 11, and has a radiation element 13, a directivity switching element 15, and polarization switching elements 16 provided on the ground conductor plate 12 side of the dielectric substrate 11. Antennas Edge | Antenna (Radio) | Polarization (Waves) Although either horizontally or vertically polarized antennas can be used for high frequencies, horizontally polarized antennas have certain advantages and are therefore preferred. ... consisting of a large number of radials extending from the base of the tower, like spokes on a wheel, ... SLOT ANTENNA consists of a metal surface, usually a ...
