Migration of wireless systems to millimeter wave frequencies requires cost reduction solutions that take advantage of the compact size, high bandwidth and extreme data rates that a high frequency operation offers. New materials with better mechanical, thermal and electrical properties are now available; fabrication processes have reached nanometric resolutions and depending on the antenna’s type, different properties can be enhanced. Multiple applications had been created around this technology, internet of things, imaging technology, biomedical applications and interferometry radars base its operation in this technology.
