Log-periodic Loop Antennas · No Login
As the frequency changes, the "active region" of the antenna shifts along the array of loops. Higher frequencies resonate with smaller loops, while lower frequencies resonate with larger ones.
Despite their smaller size, LPLAs provide wide gain-based and polarization-based bandwidths. Log-Periodic Loop Antennas
, where precise measurement in a compact space is required. As the frequency changes, the "active region" of
, have been shown to yield a gain bandwidth of approximately and a gain of 12 dB . Primary Applications , where precise measurement in a compact space is required
Like other log-periodic designs, the properties of an LPLA vary periodically with the logarithm of the frequency, allowing for consistent performance across a broad spectrum.
, where space is at a premium but wideband performance is necessary.
A log-periodic loop antenna can reduce transverse dimensions by a factor of roughly compared to an LPDA with similar radiation characteristics.
