  • Generalized Analysis Method for a Class of Novel Wideband Loaded-Stub Phase Shifters 

    Sensong An; Badar Muneer; Qi Zhu (Společnost pro radioelektronické inženýrství, 2015-12)
    In this paper, an analysis method of wideband loaded-stub phase shifters and a fast designing procedure is presented. These kinds of phase shifters use a transmission line loaded with one or two open stubs and a reference ...
  • A Novel Design of Single Branch Wideband Rectifier for Low-Power Application 

    Wu, S.; Wang, J.; Liu, J.; Cheng, D. Y; Wu, Y. B.; Li, R. F.; Li, M. Q. (Společnost pro radioelektronické inženýrství, 2020-04)
    This paper proposes a novel design of single branch wideband rectifier working at low input power level. Both the impedance tuning part and a dual-band matching network are adopted for wideband impedance matching. Theoretical ...
  • Širokopásmová vektorová měření 

    Dvořák, Radek
    Práce pojednává o návrhu a konstrukci vektorového měřícího systému pro měření impedance v širokém kmitočtovém pásmu založeném na principu tzv. šestibranu. Jsou rozebrány předpoklady pro přesné měření, metody linearizace, ...
  • Wideband High-Gain and Low Scattering Antenna Using Shared-Aperture Metamaterial Superstrate 

    Zhang, C.; Cao, X. Y.; Gao, J.; Li, S. J. (Společnost pro radioelektronické inženýrství, 2018-06)
    In this paper, a novel wideband high-gain and low scattering antenna using a shared-aperture metamaterial superstrate (SAMS) is designed, fabricated and measured. The superstrate unit cell consisting of two frequency ...
  • A Wideband Slot Antenna with Folded Parasitic Line for Multiple Band Operation 

    Mahatthanajatuphat, C.; Srisoontorn, N.; Suangun, T.; Akkaraekthalin, P. (Společnost pro radioelektronické inženýrství, 2016-12)
    The rectangular slot antenna with rectangular stub for a wide impedance bandwidth is proposed. In addition, the interference frequency band has been rejected by placing the folded parasitic line surrounding the rectangular ...
