Abstract

Polarization-dependent reflection from a finite perfect electric conducting (PEC) ground affects the polarization composition of the radiated field from a dual-polarization antenna positioned near the ground plane, especially at low elevation angles. This study employs PEC fins to control the vertically polarized radiated fields and achieve similar vertical-polarization (V-pol) and horizontal-polarization (H-pol) near horizon. As will be demonstrated from simulation results, one can efficiently control the polarization ratio of the radiated fields near horizon by adjusting the dimensions and spacing of the fins.
