Abstract
Examples disclosed herein relate to an Insulated Glass Unit (“IGU”) to enhance wireless communications in a wireless network. The IGU has a first and a second glass layers, a first and a second spacers, and a first and a second ground planes, the first ground plane in contact with the first glass layer and the second ground plane in contact with the second glass layer. The IGU also includes a gas layer in between the first and the second ground planes, a reflectarray comprising a metastructure array of reflector elements, and a third glass layer on top of the metastructure reflectarray.
Claims11
A method for designing a reflectarray for use in an insulated glass unit (IGU), comprising:
- determining a set of dimensions for the IGU, wherein the set of dimensions correspond to respective thickness of layers of the IGU;
- computing a spatial phase delay from a feed antenna;
- computing a progressive phase distribution for the reflectarray, the reflectarray comprising a metastructure array of reflector elements;
- determining dimensions for each reflector element in the reflectarray based on the progressive phase distribution;
- and
- incorporating the reflectarray in the IGU, wherein the IGU comprises:
- a first and a second glass layers;
- a first and a second spacers;
- a first and a second ground planes, the first ground plane in contact with the first glass layer and the second ground plane in contact with the second glass layer;
- a gas layer disposed in between the first and the second ground planes;
- and
- a third glass layer disposed on top of the reflectarray.
