| Leader-mw | mathematical definition of antenna |
The mathematical definition of antenna coefficient K is as follows:
The meanings of each parameter are as follows:
E: the field intensity at the spatial position of the receiving antenna, in unit of V/m;
V: voltage value received by the receiving antenna port, in unit of V.
The calculation formula of antenna coefficient expressed in logarithm is as follows:
Log-periodicDipoleAntenna use
(1) Mainly used in ultra-short wave band, can also be used as short wave communication antenna and medium wave, short wave broadcast transmission antenna. Log-periodic antennas can also be used as feeders for microwave reflector antennas. It can be used for amateur radio and citizen band radio operations, as well as scientific research and monitoring.
(2) Log-periodic Dipole Antenna, they are able to maintain consistent radiation patterns over a wide range of frequencies, making them useful in applications where antennas need to be able to work across multiple frequency bands without major adjustments or modifications
