Broadband terahertz resonant tunnelling diode transmitter integrated with coplanar‐waveguide‐fed slot‐ring antenna

Abstract Resonant tunnelling diode (RTD) oscillators used for high‐speed terahertz wireless communication systems have garnered significant attention in recent years. In these systems, RTD devices are directly on‐off modulated through baseband (BB) circuits, which limit the data rate. This letter in...
