High gain/bandwidth off-chip antenna loaded with metamaterial unit-cell impedance matching circuit for sub-terahertz near-field electronic systems
(Springer, 2022)
Artículo / Artikulua,
An innovative of-chip antenna (OCA) is presented that exhibits high gain and efciency performance
at the terahertz (THz) band and has a wide operational bandwidth. The proposed OCA is implemented
on stacked silicon layers ...
Multimode HMSIW-based bandpass filter with improved selectivity for fifth-generation (5G) RF front-ends
(MDPI, 2020)
info:eu-repo/semantics/article,
This article presents the detailed theoretical, simulation, and experimental analysis of a half-mode substrate integrated waveguide (HMSIW)-based multimode wideband filter. A third-order, semicircular HMSIW filter is ...
Monitoring of electric buses within an urban smart city environment
(IEEE, 2021)
