What Is a Log-Periodic Antenna?
A log-periodic antenna is a directional antenna known for its multi-element design, used extensively in radio communications and broadcasting.
Unlike conventional antennas featuring simple rod or wire configurations, log-periodic antennas consist of multiple elements of varying lengths and spacings arranged in a pattern resembling a scaling sequence. This design allows efficient performance across a wide bandwidth, making them versatile for various frequency ranges.
These antennas are prized for their ability to operate over a broad spectrum of frequencies with consistent gain and impedance characteristics. They excel in scenarios requiring focused transmission or reception, making them ideal for broadcasting and directional wireless communication applications. Their structured design enables strong signal amplification and targeted wave directionality.
