This paper presents a comprehensive analysis of THz proximity wireless communication comprising a resonant tunneling diode (RTD) as a solid-state signal source. For such a system, it is investigated how the RTD-based oscillator performs under direct current (DC) bias applied within the negative differential region (NDR) to provide oscillations in the THz range. Specifically, it is accounted for the DC bias effect over the reactive elements that composed the small signal model of the oscillator composed by RTD device and bowtie antenna. The mathematical formalism developed here does require the use of complicated methods to assess the current versus voltage (I-V) characteristics of the RTD-based oscillators, which makes the performance analysis straightforward. The results indicated that the RTD-based oscillator could stabilize very high frequency oscillations and the THz proximity link considered can perform error-free transmissions at the short-range link up to 27 m.
