A High-Power Terahertz Source Over 10 mW at 0.45 THz Using an Active Antenna Array With Integrated Patch Antennas and Resonant-Tunneling Diodes

Fabrication of Sub-THz Oscillators Using Resonant Tunneling Diodes Integrated with Slot Antennas

We fabricated sub-THz oscillators using resonant tunneling diodes integrated with slot antennas. Oscillations at 90GHz and 136GHz were obtained for the slot antennas with the lengths of 1mm and 800μm. Theoretical calculation shows that the maximum oscillation frequency up to ~1.2THz is expected in this structure with short antenna.

Photo-Detectors Integrated with Resonant Tunneling Diodes

We report on photo-detectors consisting of an optical waveguide that incorporates a resonant tunneling diode (RTD). Operating at wavelengths around 1.55 μm in the optical communications C band we achieve maximum sensitivities of around 0.29 A/W which is dependent on the bias voltage. This is due to the nature of RTD nonlinear current-voltage characteristic that has a negative differential resis...

an infinite planar array of rectangular microstrip patch antenna analysis

the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...
