"This paper describes a reconfigurable millimeterwave lens-array antenna based on monolithically integrated microelectromechanical systems (MEMS) switches. This device is constructed as a planar array of 2-bit programmable MEMS antenna-filter-antenna (AFA) unit cells that are used to provide a 1-D programmable ''aperture transfer function'' between the input and output wavefronts," researchers in the United States report.
"The fully integrated device consists of 484 (22 x 22) AFA elements and 2420 switches. Switches, bias lines, antennas, and the rest of the RF structure are fabricated on two quartz wafers (epsilon(r) = 3.8, tan delta = 0.002) that are ...
