If the perimeter of a loop antenna is much smaller than the intended operating wavelengths – say 1 / 3 to 1 / 100 of a wavelength – then the antenna is called a small loop antenna. Several performance factors, including received power, scale in proportion to the loop's area. Ver mais A loop antenna is a radio antenna consisting of a loop or coil of wire, tubing, or other electrical conductor, that is usually fed by a balanced source or feeding a balanced load. Within this physical description there are … Ver mais A halo antenna is often described as a half-wave dipole antenna that has been bent into a circle. Although it could be categorized as a bent dipole, it has the omnidirectional radiation pattern very nearly the same as a small loop. The halo is more Ver mais Some antennas look very much like loops, but are designed to couple with the inductive near-field – over distances of a meter (3.3 feet) or two (6.6) – rather than to transmit or receive long-distance electromagnetic waves in the radiative far-field.

Retrieved 2024-10-14.{{ Ver mais For all of the large loops described in this section, the radio's operating frequency is assumed to be tuned to the loop antenna's first resonance. At … Ver mais Small loops are small in comparison to their operating wavelength. Contrary to the pattern of large loop antennas, the reception and radiation strength of small loops peaks inside the plane of the loop, rather than broadside (perpendicular) to it. As with all antennas … Ver mais 1. ^ The antenna can be described as "self-resonant" in the sense that if you short the antenna terminals, then a current in the loop will be created in response to an electromagnetic wave, and the relative magnitude of that current will be greatly increased around … Ver mais WebOverview.
