Log Periodic Dipole Array

A type of directional, wideband antenna that consists of a series of dipole elements of varying lengths, arranged in such a way that the size and spacing of the elements increase logarithmically along the antenna boom. This unique design allows the antenna to operate efficiently over a broad range of frequencies. Unlike traditional single-band antennas, an LPDA does not have a fixed resonant frequency. Instead, it resonates at a multitude of frequencies within its operating band, providing consistent performance across a wide frequency spectrum. These properties make LPDAs particularly useful in applications requiring broad frequency coverage, such as in broadcasting and telecommunications, and highly popular as a 4G-5G receiving antenna.
