Microstrip-fed Triangular UWB Microstrip Antenna Based on DGS

International Journal of Applied Mathematics, Electronics and Computers, 2016
An ultra-wideband (UWB) monopole microstrip antenna is designed in this study. The design consists of a radiating triangular patch antenna (TPA) fed through a 50 Ohm microstrip transmission line (MTL) constructed over a defected ground structure (DGS). The triangular monopole well is matched to MTL with inserting a thin strip line.

Reconfigurable Terahertz Multi‐Harmonic Dual‐Combs

Nanophotonics, Volume 15, Issue 17, 11 September 2026.
Terahertz dual‐comb spectroscopy requires precise control of repetition frequencies. A reconfigurable dual‐comb system is realized on a single self‐detected quantum cascade laser platform, where harmonic order serves as a new tuning parameter. Switching among fundamental and harmonic states enables flexible multi‐heterodyne down‐conversion without ...
