On design of differentially driven on-chip antennas with harmonic filtering for silicon integrated mm-wave and THz N-push oscillators

This paper reports on design of differentially driven lens-integrated on-chip ring antennas with harmonic filtering for both CMOS and SiGe HBT highly integrated mm-wave and THz N-push oscillators. Two state-of-the-art circuit/ antenna co-design examples of high-power sources are presented: at 288 GHz in 65nm CMOS technology and at 530 GHz in 0.13μm SiGe BiCMOS technology. The 530 GHz version is additionally extended into a 4×4 array with configurable radiation pattern diversity and capable of providing a total radiated power of up to 1mW.
