Keywords:
Antenna, Directivity, Log-periodic, Radar technologies, Radiation patternAbstract
The log-periodic antenna (LPA) is a frequency-independent antenna widely used in broadband applications due to its unique design and radiation characteristics. This review explores the radiation pattern of log-periodic antennas, focusing on their directivity, gain, beamwidth, and polarization across different frequency ranges. The study highlights the fundamental principles governing LPAs, including their self-similar structure, which ensures consistent performance over a wide frequency spectrum. Unlike conventional antennas, LPAs exhibit stable radiation patterns with minimal variation in beamwidth, making them suitable for applications such as telecommunications, radar, and electromagnetic compatibility testing. Advancements in antenna technology have led to modifications in LPA design, such as the use of fractal and reconfigurable structures, which further improve bandwidth and radiation stability. This review also compares LPAs with other broadband antennas, emphasizing their advantages in terms of frequency coverage, impedance matching, and radiation efficiency. Finally, future research directions are suggested, including the integration of LPAs in modern wireless communication systems and next-generation radar technologies.
