Abstract

In an example implementation, an antenna assembly includes an antenna array, a dielectric cover, and a superstrate metal patch with coupling lines. The superstrate metal patch with coupling lines is placed under the dielectric cover and about λ/2 above the antenna array. λ is wavelength of operating frequency of the antenna array. The coupling lines are connected to the superstrate metal patch, and the coupling lines are extended from the superstrate metal patch.
