Abstract
Examples disclosed herein relate to reflectarray antenna for enhanced wireless applications. The reflectarray antenna has a ground conductive plane, a dielectric substrate coupled to the ground conductive plane, and a patterned conductive plane coupled to the dielectric substrate and comprising an array of cells to generate an antenna gain. In some aspects, each cell in the array of cells includes a reflector element with a predetermined custom configuration and configured to receive a radio frequency (RF) signal and to generate an RF return beam at a predetermined direction. Other examples disclosed herein relate to a portable reflectarray and a method of fabricating a reflectarray antenna.
Claims11
A reflectarray for use in a millimeter wave wireless communication system, the reflectarray comprising:
- an array of cells configured in a patterned conductive layer disposed on top of a dielectric substrate, each cell of the array of cells comprising a meta-structure (MTS) reflector element, wherein at least one cell of the array of cells comprises a hexagonal reflector element, at least one cell of the array of cells comprises a rectangular reflector element, at least one cell of the array of cells comprises a dipole reflector element;
- and
- a removable cover that is non-permanently coupled to the patterned conductive layer.
