SAMBA: Superconducting antenna-coupled, multi-frequency, bolometric array [PDF]
, 2002 We present a design for a multipixel, multiband (100 GHz, 200 GHz and 400 GHz) submillimeter instrument: SAMBA (Superconducting Antenna-coupled, Multi-frequency, Bolometric Array). SAMBA uses slot antenna coupled bolometers and microstrip filters.

Diced and grounded broadband bow-tie antenna with tuning stub for resonant tunnelling diode terahertz oscillators [PDF]
, 2016 Radiation from antennas integrated with indium phosphide (InP)-based resonant tunnelling diode (RTD) oscillators is mainly through the substrate because of the effects of the large dielectric constant.

Linear Array of Center Line Longitudinal Slots Excited by Double Ridge Waveguides [PDF]
Radioengineering, 2018 Slot antennas fed by the wiggly ridge wave¬guides are difficult to construct using a typical milling machine. Therefore, a special type of the double ridge waveguides is introduced here to feed the center line longi¬tudinal slot antennas. Furthermore, in
