Optimum power transfer in RF front end systems using adaptive impedance matching technique
(Nature Research, 2021)
Artículo / Artikulua,
Matching the antenna’s impedance to the RF-front-end of a wireless communications system is challenging as the impedance varies with its surround environment. Autonomously matching the antenna to the RF-front-end is therefore ...
Analysis of the combinatory effect of uniaxial electrical and magnetic anisotropy on the input impedance and mutual coupling of a printed dipole antenna
