The log periodic antenna was initially developed by Dwight E. Log periodic antenna used for television reception Although larger than an equivalent Yagi or other directive design for an equivalent level of gain, it provides the capability to operate on many different frequencies. One form of antenna that is able to provide gain and directivity along with a wide bandwidth is known as the log periodic antenna. Log periodic antenna basics Log periodic theory & equationsÄirective antennas like the Yagi provide gain and directivity but their bandwidth is limited. Log Periodic Antenna / Aerial The log periodic antenna or aerial often called the LPDA is a wideband directional antenna that provides gain and directivity combined over a wide band of frequencies.
