Experimental and theoretical characteristics of sub-THz and THz oscillation of resonant tunneling diode integrated with slot antenna

Sub-THz and THz oscillation of resonant tunneling diodes integrated with slot antennas is investigated. Oscillation frequency of 587 GHz in the experiment agrees very well with theoretical analysis which indicates possibility of oscillation up to 1.4 THz by reducing antenna size. Output power of 50 /spl mu/W around 1 THz is also estimated theoretically.
