340 GHz Single-Layer Antenna on Chip (AoC) Using Higher Order Mode Resonance Cavities

Antenna on Chip (AoC) provides a promising solution to reduce the interconnection loss between on-chip system circuits and off-chip antennas in terahertz (THz) bands. In this paper, a 2 ×2 slot array on chip along with its modified version of L-shape slots are presented and designed. Two parallel $\text{TH}_{20}$ 1 resonant cavities are employed to feed the slot array and both higher order resonant modes are excited by a grounded coplanar waveguide (GCPW). The proposed antenna features a simple array feeding network and high gain, making it a viable option for THz communication and radar applications.
