Focused source formation using a micro disc-like patch antenna array for THz CMOS transceiver applications

The paper presents a scheme to generate a focused THz source using a disc-like antenna array for THz CMOS-based transceiver application. The disk-like antenna array is fabricated by pressing a steel ball onto a flexible flat antenna array placed on a hollow silicon mold to form a hemispherical shell disk. Simulation results show that the receiving power from the center of the disc-like patch antenna array can improve the ratio of the receiving power to the incident one from 0.064 to 0.101 in comparison with that from the flat antenna array. About 1-2 dB receiving power difference measured experimentally has also validated the source focusing capability via the scheme.
