Dielectric lens antennas for 300-GHz applications

Implementation of proper wireless links at submillimetre-wave and terahertz (THz) frequencies requires high-gain antennas. This simulation-based study investigates the performance of dielectric lenses and their feed antennas at 300 GHz. Parametric studies and electromagnetic simulations are used to determine the general lens properties, and the use of waveguide and on-chip antenna feeds is considered. The results show that the studied lens and feed structures can provide good, directive radiation patterns also with beam scanning.
