  • Comparison of Planar Fractal Filters on Defected Ground Substrate 

    Kufa, M.; Raida, Zbyněk (Společnost pro radioelektronické inženýrství, 2012-12)
    The paper discusses approaches to the reduction of dimensions of planar filters (microstrip ones and coplanar ones). Filter dimensions are reduced by applying the fractal theory to the geometry of a filter, and by the ...
  • Defected Ground Structure toward Cross Polarization Reduction of Microstrip Patch Antenna with Improved Impedance Matching 

    Acharjee, J.; Singh, A. K.; Mandal, K.; Mandal, S. K. (Společnost pro radioelektronické inženýrství, 2019-04)
    A new approach based on the incorporation of Z-shaped defected ground structure (DGS) in microstrip antenna (MSA) for improving impedance matching and cross polarization (XP) performances is proposed in this paper. Through ...
  • Design of High Performance Microstrip Dual-Band Bandpass Filter 

    Khajavi, N.; Makki, S. V.; Majidifar, S. (Společnost pro radioelektronické inženýrství, 2015-04)
    This paper presents a new design of dual-band bandpass filters using coupled stepped-impedance resonators for wireless systems. This architecture uses multiple couple stubs to tune the passband frequencies and the filter ...
  • High Performance DGS Integrated Compact Antenna for 2.4/5.2/5.8 GHz WLAN Band 

    Chakraborty, M.; Chakraborty, S.; Reddy, P. S.; Samanta, S. (Společnost pro radioelektronické inženýrství, 2017-04)
    An application specific tri-band hexagonal microstrip antenna with saw tooth shaped defected ground structure (DGS) is proposed. In this paper, a hexagonal microstrip antenna is designed for 5.2 GHz which is basically WLAN ...
  • MIKROPÁSKOVÉ FILTRY S VYUŽITÍM NARUŠENÉ ZEMNÍ PLOCHY 

    Vágner, Petr
    Tato práce se zabývá možností využití narušené zemní plochy (DGS) při návrhu mikropáskových filtrů, založených na technologii nesymetrického mikropáskového vedení. Zemní rovina není (jako u klasického mikropáskového vedení) ...
  • Modeling of Modified Split-Ring Type Defected Ground Structure and Its Application as Bandstop Filter 

    Parui, S. K.; Das, S. (Společnost pro radioelektronické inženýrství, 2009-06)
    The shape of a popular split-ring defected ground structure (DGS) is modified by selecting different width of the sides with respect to microstrip line. The frequency characteristics of proposed DGS unit show an attenuation ...
  • Novel Fractal DGSs for Band-gap Filter with Improved Q-factor 

    Gong, Y. Y.; Wang, L.; Wei, K.; Zhang, Z. L. (Společnost pro radioelektronické inženýrství, 2017-12)
    This paper presents a novel fractal defected ground structure (FDGS) for designing high Q-factor band-gap filter. Key parameters of the proposed FDGS are studied. The decreased slot distance causes rapid increase in the ...
