As a leading LPDA Antenna Manufacturer based in China, Asian Creation Communication has over two decades of expertise in designing and manufacturing high-performance log-periodic dipole array (LPDA) antennas.
LPDA antennas are extremely wideband directional antennas with a simple yet robust structure, capable of converting electromagnetic waves into electrical signals and vice versa. Thanks to their broadband coverage, stable gain, and excellent front-to-back ratio, they are widely used in military, commercial, and industrial wireless communication systems.
Working Principle
The LPDA antenna consists of multiple dipole elements of varying lengths, mounted along a supporting boom and fed by a transmission line with alternating connections. This unique geometry allows the antenna to operate across a broad frequency range while maintaining consistent impedance and directional characteristics.
The "active region" of the LPDA shifts with frequency, enabling superior performance across VHF, UHF, and microwave bands.
