Abstract

This study investigates the polarization characteristics of a multilevel log-periodic antenna designed for DVB-T2 systems. Based on a two-level structure arranged orthogonally, the formation of circular polarization was confirmed through both simulation and experimental methods. Measurement results show stable antenna performance in the 470–860 MHz frequency range and improved key electromagnetic parameters. The proposed antenna is an effective solution for enhancing signal quality under multipath propagation conditions.
