Abstract
As the need for higher connectivity is pushing to open up higher frequency bands for communications, entering the micro and millimeter wave bands (>10 GHz), we are facing the need to develop new antennas to cope with two main requirements: low cost and reconfigurability. Low-cost is a must as the band from 28 to 40 GHz is seriously considered to bridge end mobile users, and this implies large deployments, inherently cost sensitive. Reconfigurability is a must as once deployed, such systems need to be able to adjust to the peculiarities of their environment and traffic needs. Horn antennas based on metal drilling and milling are technology and cost intensive, while not allowing reconfigurability once fabricated. In this paper, we will review our recent work in using advanced materials for antenna reconfigurability and fabrication. The results enable advanced functionalities such as frequency switching and beam forming.
