What is a biconic antenna?
biconical antenna is a conductor that can send and receive signals from two fields in the shape of a cone that spreads against each other. It is usually in the shape of an hourglass, because both wires have a common axis and balun. These broadband dipole antennas work in the range of 30 to 300 megahertz (MHz), although they range from 20 MHz to 3 Gigahertz (GHz). They may have a bandwidth of three or more octaves.
biconic antennas, sometimes called bicons, are basically two cones touching points with a regular central axis. Each cone applies excitation at its peak or point. These components can be powered by electronic charges, potentials or alternating magnetic fields and currents at the top. When only one cone is tilted or at 180 degrees, it is referred to as Discone. Balun, abbreviation for balance/imbalance, is an atransformer bond that converts current balances for impedance regulation concerning the relationship between current, voltage, resistance and their effectKY on the profile of the radiation profile of the antenna. Balun helps to determine the radiation formula and the antenna efficiency. The elements symmetrically radiate from their holder, although there are cylindrical and star varieties.
Often the biconic antenna is used in testing electromagnetic interference (EMI), immunity or emission testing. These tests occur at 25-200 MHz for commercial applications and 30-200 MHz for the army. The dipole and yagi fields indicate higher field forces than a simple biconic antenna; Bicon is less efficient, but has a broadband range. Simple conical monopolies and bowtie antenna, approximation of biconical wire type, have increased bandwidth compared to monopoly. High -profit antennas usually have the income of signal strength, while low -profit varieties such as bicon are transmitted over a wider angle.
with conductors radiating from the central point in the opposite directions, the design causes the biconic antenna to be well suitable for ProReading measurement and compliance testing. It is also beneficial for the service of automated antenna measurement systems. Its advantage over the measurement of the attenuation of the vertical place or the loss of the signal is attributed to its long lengths of dipole element at lower frequencies: for example, 16.4 feet (about 5 m) at 30 MHz.
Some designs allow vertical and horizontal sweeping of attenuation measurement. The symmetrical Bicon design allows a more consistent repetition of the test because the antenna is not affected by the way it turns. For these applications, manufacturers will sometimes provide calibration data for measurement standards; For example, the profit and antennas factor versus frequency.
Usually the radiation formula of the biconic antenna appears to be similar to that of dipole antennas, with a field pattern extending in contradictory dual lobes. These patterns work practically independently of frequency. Common applications include use in areas that require omnidirectional radiation as well as in EM testing devicesisi; It fulfills the obligation on land and mobile platforms and on aircraft. Smaller sizes allow versatile portable use, as these antennas tend to be low and easily set up.
