Abstract
On-chip antennas operating in the THz frequency range are characterized by narrow bandwidth and poor radiation efficiency. This is because they are electrically very close to the ground plane that is used to shield the antenna from the lossy substrate. In this work we propose a novel approach to increase the efficiency and the bandwidth of antennas integrated on chip, by exploiting and combining the two concepts of connected arrays and artificial dielectric layers.
