TV Antenna With Megnetic Base. LogPeriodic Dipole Array Calculator Author. Lpdipole lpda NameValue sets properties using one or more name-value pairs.

The actual bandwidth achieved is dependent on how large the structure is to determine the lower frequency limit and how precise the finer smaller features are on the antenna which determines the upper frequency limit. Log-Periodic antennas antennas are designed for the specific purpose of having a very wide bandwidthThe achievable bandwidth is theoretically infinite. In the far-field the radiation pattern does not change shape as the distance increases.

Its advantage is that it exhibits essentially constant characteristics over the frequency range which has the same radiation resistance and the same pattern. Serge Stroobandt ON4AA Subject. By Avon ampo Monday October 5 2015.

The main category is Log Periodic Antenna projects that is about Log Periodic Antennas. Log Periodic Dipole Arrays or LPDA is a directional antenna with relatively constant characteristics across its wide frequency range. Increasing τ to 09 from 087 will result in a 14-foot 25-element LPDA which is still practical.

Please refer to the ARRL Antenna Book 22nd Edition Chapter 7 for explanations of equations. 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. 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.

Following the angle concept if one tooth has a width the next smaller one is wide the third is and so on. Let the width of the widest tooth be which is approximately one quarter wavelength.

The design based on the concept of the log-periodic structure was the log-periodic toothed Planar antenna.
