  • The ANTENNA (from an armour. antenna - a spar tree, rej), in a wireless - the device intended (it is routine in combination to a radio transmitter or a radio receiver) for radiance or (รจ) method of radiowaves. One of basic performances of the antenna - the directional diagram (BOTTOMS) defining character of a spatial distribution of power of an electromagnetic field, radiated (received) by the antenna. Distinguish antennas non-directional (shirokonapravlennye) and directed (napr., antennas with pencil-beam the BOTTOMS, called as a ray). With the help of antennas it is possible to accept very weak radio signals, to execute directed drive and signal detection, to locate sources of radiowaves, etc. Versions of antennas: dipole (wire), fissured, horn, reflecting, lens, antenna arrays, etc.
  • ANTENNAS (horns, tendrils), multijointed mobile head appendages for arthropods (excluding arachnids). For the majority - sense bodys.
