Dostáváme dotazy, ohledně polarizace antén, tak jsem se rozhodl k tomu napsat pár odpovědí na nejčastější dotazy A circularly polarized wave can rotate in one of two possible senses: clockwise or right-handed circular polarization (RHCP) in which the electric field vector rotates in a right-hand sense with respect to the direction of propagation, and counter-clockwise or left-handed circular polarization (LHCP) in which the vector rotates in a left-hand sense. Circular polarization is a limiting case of. Note that the IEEE defines RHCP and LHCP the opposite as those used by Physicists. The IEEE 1979 Antenna Standard will show RHCP on the South Pole of the Poincare Sphere. The IEEE defines RHCP using the right hand with thumb pointing in the direction of transmit, and the fingers showing the direction of rotation of the E field with time. The rationale for the opposite conventions used by Physicists and Engineers is that Astronomical Observations are always done with the incoming wave.
Abkürzungen: RHCP und LHCP für rechts- oder linkshändige Polarisation (eng. Right Hand Circular Polarization und Left Hand Circular Polarization). elliptische Polarisation ist eine Mischform. Die Auslenkung beschreibt dabei eine Ellipse. Mathematische Beschreibun Der Antennengewinn fasst die Richtwirkung und den Wirkungsgrad einer Antenne zusammen. Er ist das Verhältnis der in Hauptrichtung abgegebenen resp. aufgenommenen Strahlungsleistungsdichte, verglichen mit einer verlustlosen Bezugsantenne gleicher Antennenspeiseleistung, die definitionsgemäß einen Antennengewinn von 0 dB hat. Als Bezugsantenne wird meist ein hypothetischer Isotropstrahler mit in allen Richtungen gleicher Strahlstärke gewählt oder eine Dipolantenne. Parabolantenn In telecommunication, a microstrip antenna usually means an antenna fabricated using photolithographic techniques on a printed circuit board. It is a kind of internal antenna. They are mostly used at microwave frequencies. An individual microstrip antenna consists of a patch of metal foil of various shapes on the surface of a PCB, with a metal foil ground plane on the other side of the board. Most microstrip antennas consist of multiple patches in a two-dimensional array. The antenna is usuall
A helical antenna is an antenna consisting of one or more conducting wires wound in the form of a helix. A helical antenna made of one helical wire, the most common type, is called monofilar, while antennas with two or four wires in a helix are called bifilar, or quadrifilar, respectively. In most cases, directional helical antennas are mounted over a ground plane, while omnidirectional designs may not be. The feed line is connected between the bottom of the helix and the ground plane. Helical . Most commonly it is used to pilot a radio-controlled aircraft or other type of unmanned aerial vehicle (UAV). The vehicle is either driven or piloted remotely from a first-person perspective via an onboard. Horizontal vs. vertical is more about ground gain and takeoff angle on HF. Now if grt to circular polarisation then you can get advantages. A bit more gain and much less fading
In electromagnetics, an antenna's power gain or simply gain is a key performance number which combines the antenna's directivity and electrical efficiency. In a transmitting antenna, the gain describes how well the antenna converts input power into radio waves headed in a specified direction. In a receiving antenna, the gain describes how well the antenna converts radio waves arriving from a specified direction into electrical power. When no direction is specified, gain is understood to refer t In microwave systems, a spiral antenna is a type of RF antenna. It is shaped as a two-arm spiral, or more arms may be used. Spiral antennas were first described in 1956. Spiral antennas belong to the class of frequency independent antennas which operate over a wide range of frequencies. Polarization, radiation pattern and impedance of such antennas remain unchanged over large bandwidth. Such antennas are inherently circularly polarized with low gain. Array of spiral antennas can be used to incr Iridium Communications Inc. (formerly Iridium Satellite LLC) is a publicly traded American company headquartered in McLean, Virginia.Iridium operates the Iridium satellite constellation, a system of 66 active satellites (and 9 spares in space) used for worldwide voice and data communication from hand-held satellite phones and other transceiver units
Path loss of radio transmitted through air or vacuum In telecommunication, the free-space path loss is the attenuation of radio energy between the feedpoints of two antennas that results from the combination of the receiving antenna's capture area plus the obstacle-free, line-of-sight path through free space. The Standard Definitions of Terms for Antennas, IEEE Std 145-1993, defines free-space loss as The loss between two isotropic radiators in free space, expressed as a power ratio. It d In optics, polarized light can be described using the Jones calculus, discovered by R. C. Jones in 1941. Polarized light is represented by a Jones vector, and linear optical elements are represented by Jones matrices. When light crosses an optical element the resulting polarization of the emerging light is found by taking the product of the Jones matrix of the optical element and the Jones vector of the incident light. Note that Jones calculus is only applicable to light that is already fully p
