When designed with a ground reflector, they offer linear polarization and unidirectional patterns, making them excellent candidates for mobile communications and EMC measurement detectors. Technical Characteristics
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. Log-Periodic Loop Antennas
Because of their high gain and compact form factor, LPLAs are frequently used as: . When designed with a ground reflector, they offer
An interesting feature of is their ability to achieve a significant size reduction (specifically in transverse dimensions) compared to standard log-periodic dipole antennas (LPDA) while maintaining high gain and wide bandwidth. Key Feature: Compact Lateral Footprint Because of their high gain and compact form
Advanced configurations, such as a 6-turn LPLA with a cone angle of 30∘30 raised to the composed with power
The most distinctive advantage of the LPLA is its physical compactness. Researchers have found that:
Despite their smaller size, LPLAs provide wide gain-based and polarization-based bandwidths.
