Abstract
The present disclosure is directed to an antenna cover comprising a layer including a polymer composition. The polymer composition comprises a polymer matrix containing at least one polymer having a glass transition temperature of about 50° C. or more wherein the polymer matrix constitutes from about 30 wt. % to about 90 wt. % of the polymer composition. The polymer composition exhibits a dielectric constant of about 4 or less and a dissipation factor of about 0.02 or less, as determined at a frequency of 2 GHz. The present disclosure is also directed to a 5G radio frequency communication device and a base station including the aforementioned antenna cover.
