We propose and fabricate a novel structure-simplified resonant tunneling diode (RTD) terahertz (THz) oscillator without metal-insulator-metal (MIM) capacitors. In conventional RTD THz oscillators, the DC and RF circuits are separated by MIM capacitors. In the proposed oscillator, the DC-to-RF separation is based on the difference between the impeda...

... With the use of shorting pins, the gain and radiation efficiency are improved from 3.497dB to 3.5dB, and 55.71% to 55.88% , respectively when compared without the use of shorting pin. A simple bowtie antenna, on an InP substrate is simulated to operate at 300GHz [4]. Although its bandwidth is wider, but the radiation pattern is highly degraded due to the high value of relative permittivity of InP. ...
