Design of a printed 5g monopole antenna on vehicle window glass using parasitic elements and a lattice-structure reflector for gain enhancement

초록

This letter proposes a novel design for a printed 5G monopole antenna on a vehicle window glass. The proposed antenna consists of a coplanar waveguide (CPW), a monopole radiator, parasitic elements, and a lattice-structure reflector. The parasitic elements are placed on either side of the monopole radiator to improve the bore-sight gain. To solve the radiation pattern distortion problem that occurs due to the thick vehicle window glass, the lattice-structure reflector is printed on the opposite side of the monopole radiator. Through fabrication and measurement of the proposed antenna, it is confirmed that the design improves bore-sight gain, and minimizes the radiation pattern distortion. The results demonstrate that the proposed 5G monopole antenna with parasitic elements and the lattice-structure reflector is suitable for 5G communication in vehicle applications. © 2021 by the authors.
