This paper presents a design of 484GHz on-chip antenna for THz direct detector in TSMC 0.18µm standard CMOS technology. The on-chip patch antenna fed by microstrip transmission lines is designed and simulated by Ansoft HFSS. To improve the power transfer efficiency, an open-stub matching network is inserted between the antenna and the detector. The peak gain of the antenna is 3 dBi, The bandwidth...
In this presentation, we will provide an overview on the research activities on terahertz (THz) science and technology recently conducted at the State Key Laboratory of Millimeter Waves (SKLMW), Partner Laboratory in City University of Hong Kong. SKLMW was established in 2008 with the approval of the Ministry of Science and Technology and our partner is the State Key Laboratory of Millimeter Waves...
A cavity-backed loop antenna is presented for radiating circular polarization (CP) waves and gain enhancement. The antenna is double-side printed on a substrate. It consists of two pairs of orthogonal dual square loops fed in parallel. It satisfied self-phase shift to radiate CP waves, as the smaller loop has a 90° phase ahead of the larger loop. With two more loops than dual-loop antenna, the gain...
