초록/요약
In this thesis, monolithic terahertz sources and antenna using Teledyne InP 250-nm DHBT and Samsung 65-nm CMOS process are introduced. For terahertz sources, high power 600 GHz multiplier and 300 GHz voltage controlled oscillator using InP DHBT are fabricated and measured offering output power of -8 dBm at 600 GHz and 5.8 dBm at 300 GHz, respectively. Additionally, low cost 600 GHz multiplier using CMOS varactor showing -20.9 dBm of output power is also demonstrated. For terahertz on-chip antenna, a cavity antenna using only standard InP environment is developed with on-wafer far-field measurement method. The cavity antenna provide more than 50% of efficiency within 20 GHz of bandwidth around 280 GHz unlike the patch antenna offers 20% of peak efficiency with less than 10 GHz of bandwidth. Moreover, a multi-mode cavity antenna and a cavity-backed wire array antenna are demonstrated in an attempt to improve bandwidth and cope with cut-off problem caused by cavity depth shortage, respectively. For the last chapter, far-field measurement method using standard on-wafer probe measurement system to characterize antenna efficiency and radiation pattern of on-chip antenna is described.
