Abstract
Methods, systems, and apparatuses, for a millimeter wave filter array are discussed. The filter array includes an array of unit cells formed using a dielectric layer of a dielectric material, the dielectric layer having a first surface and an opposing second surface. Each unit cell includes conductive sidewall layers extending at least partially between the first surface and the second surface of the dielectric layer and defining a resonant space within the dielectric layer. Each unit cell also includes a metallized layer formed on the first surface, covering at least a portion of the resonant space of the dielectric layer and electrically connected to the conductive sidewall layers. Each unit cell includes a radio-frequency input-output (RF I/O) contact formed on the first surface of the dielectric layer.
