Abstract
In this paper, we propose a design for an on-glass 5G monopole antenna for a vehicle window glass. The proposed antenna consists of a monopole resonator, an inductive line, and a co-planar waveguide (CPW), which can adjust the phase so that the current in each resonator is close to in phase. Therefore, although the vehicle window glass has a high dielectric loss, the proposed monopole with an inductive line can obtain an antenna gain that is suitable for applying to vehicle 5G communications. To verify the antenna characteristics, the reflection coefficients and the radiation patterns are measured in a full anechoic chamber. The results demonstrate that the proposed on-glass antenna is suitable for applying in vehicle 5G communications.

Summary
The demand has been progressively increasing for a vehicle-to-everything (V2X) communication technology to improve the level of autonomous driving technology [1]−[4]. To apply 5G techniques to an autonomous vehicle, a high-gain 5G array antenna must be mounted on a small area of the vehicle. Since a number of antennas (e.g., DMB, GPS, and LTE) are already built-in in the shark-fin housing, there is not enough space to insert an additional high-gain 5G array antenna without performance degradation from mutual coupling effect with adjacent antennas. The glass antenna can be made within the manufacturing process of the vehicle window glass For these reasons, a glass antenna can be considered as a noteworthy candidate antenna type for applying in vehicle wireless communications, thick glass windows with high dielectric loss characteristics does not help the performance of the 5G antenna at all.
