Antenna is a converter (usually linear) of wave fields; in the traditional sense - a device designed to emit or receive radio waves.
The transmitting antenna converts the guided electromagnetic waves moving from the radio transmitter along the feeder line to the antenna input into free electromagnetic waves diverging in space. The receiving antenna converts the free waves incident on it into guided feeder waves, which supply the received energy to the input of the radio receiver: 5.
The first transmitting antenna was created by Heinrich Hertz in 1886-1888 during his experiments to prove the existence of electromagnetic waves (Hertz vibrator, dipole antenna).
The design and dimensions of antennas are extremely diverse and depend on the operating wavelength and purpose of the antenna. Antennas made in the form of a piece of wire, a system of conductors, a metal horn, metal and dielectric waveguides, waveguides with metal walls with a system of cut slots, and many other types have found wide application. To improve the directional properties, the primary emitter can be equipped with reflective elements (reflectors), as well as lenses.
The Pitó tube is a device for measuring the total pressure of a flowing liquid (suspension) or gas. It is named after its inventor (1732), the French hydraulic engineer Henri Pitot.
The pressure (pneumometric, or full pressure tube) Pitot tube is connected to special instruments and devices. It is used to determine the relative velocity and volume flow in gas ducts and ventilation systems, complete with differential pressure gauges.
It is used as an integral part of the Prandtl tube in aviation air pressure receivers for the possibility of simultaneously determining the speed and flight altitude.
