What is a LPDA Antenna?
An LPDA (Log Periodic Dipole Array) antenna is a type of directional antenna consisting of multiple dipole elements arranged in a logarithmic pattern. This design allows the antenna to operate efficiently across a wide frequency range with nearly constant performance characteristics.
Unlike narrowband antennas, LPDA antennas provide broadband performance, making them ideal for applications where multiple frequency bands are required without frequent tuning.
