A log-periodic antenna also known as a log-periodic array or aerial is a directional and narrow beam antenna that operates over a wide bandwidth. Other options in the SAVE-NEC option include changing the polarity from. And because the antenna designs discussed earlier are based upon resonant elements off-resonance operation introduces reactance which causes the SWR in the feeder system to increase.
Its advantage is that it exhibits essentially constant characteristics over the frequency range which has the same radiation resistance and the same pattern characteristic with approximately the. This link is listed in our web site directory since Sunday Oct 28 2007 and till today Log Periodic Antenna Design has been followed for a total of 34284 timesSo far received 283. Log Periodic Dipole Arrays or LPDA is a directional antenna with relatively constant characteristics across its wide frequency range.
Before you start constructing your own LPDA using the LPDA calculator below please read chapter 10 of the 20th Edition of the ARRL Antenna Book Other editions of the ARRL Antenna Book work as well but may. From the design frequency of the array. 2 by Dennis Miller KM9O.
LogPeriodic Dipole Array Calculator Author. Far field Distance - The far-field distance is the distance from the transmitting antenna to the beginning of the Fraunhofer region or far-field. As may be seen in Fig1 the log-periodic array consists of several dipole elements which.
