Abstract
A communication device and method of forming the device are described. The device includes a mm Wave antenna on a substrate and glass cover protecting the substrate. A metasurface having a periodic set of unit cells is disposed on a surface of the substrate. A filter disposed between the unit cells has a sub-6 GHz passband. The metasurface has a structure that is designed to mitigate deleterious effects caused by the presence of the glass cover in close proximity to the mm Wave antenna.

A combined antenna structure comprising:
- a mmWave antenna configured to emit radiation in a mmWave band;
- a dielectric substrate separated from the mmWave antenna by a predetermined distance in a direction substantially perpendicular to a surface of a supporting substrate on which the mmWave antenna is disposed;
- and
- a conductive metasurface disposed on the dielectric substrate to cover the mmWave antenna in a plane substantially parallel to the surface of the supporting substrate, the metasurface comprising a substantially two-dimensional structure configured to mitigate effects of the dielectric substrate on a gain pattern of the mmWave antenna.
A modified dielectric structure comprising:
- a glass substrate;
- and
- a conductive metasurface disposed on the glass substrate, the metasurface comprising a substantially two-dimensional structure configured to mitigate effects of the glass substrate on a gain pattern of a mmWave antenna.
A communication device comprising:
- a housing in which is disposed:
- a sub-6 GHz antenna configured to emit radiation in a sub-6 GHz band;
- a dielectric substrate on which a mmWave patch antenna configured to emit radiation in a mmWave band is disposed;
- and
- a processor configured control communications using the sub-6 GHz antenna and the mmWave patch antenna;
- a glass cover surrounded by the housing and separated from the dielectric substrate by a predetermined distance in a direction substantially perpendicular to a surface of the dielectric substrate on which the mmWave patch antenna is disposed;
- and
- a conductive metasurface disposed on the glass cover to cover the mmWave patch antenna in a plane substantially parallel to the surface of the dielectric substrate, the metasurface comprising a substantially two-dimensional structure configured to mitigate effects of the glass cover on a gain pattern of the mmWave patch antenna.
