    Diseño de filtros paso bajo usando Defected Ground Structures (DGS)
    (2003) Garde Irigoyen, Ieltxu Aitor; Río Bocio, Carlos del; Ingeniería Eléctrica y Electrónica; Ingeniaritza Elektrikoa eta Elektronikoa
    In this paper a new method of trully design of filters using Defected Ground Structures is proposed. It makes use of the model proposed in previous developments by the same authors and simplifies it to a first-order model formed only by an inductor. This is done in order to make the process easier and more straight-forward. The tabulation of the inductors which are equivalent to DGS is made varying the perimeter. This allows us to connect to the classical theory and therefore to design any desired filter. The results obtained are very good and can be applied to other cases.

    A stopband filter design using a 1-D non-periodic defected ground structure
    (Wiley, 2003) Garde Irigoyen, Ieltxu Aitor; Río Bocio, Carlos del; Ingeniería Eléctrica y Electrónica; Ingeniaritza Elektrikoa eta Elektronikoa
    The one-dimensional (1-D) defected ground structure is used to control the cutoff frequency characteristic. In this paper three non-periodic filters are built, in order to show the versatility of the DGS. Five unit cells different in shape with the same attenuation pole frequency were combined in each filter. The frequency response is essentially the same as for the case of periodic filters with equal square unit cells.

    Simple modelling of DGS to design 1D-PBG low-pass filters
    (Wiley, 2003) Garde Irigoyen, Ieltxu Aitor; Yábar, Miguel Javier; Río Bocio, Carlos del; Ingeniería Eléctrica y Electrónica; Ingeniaritza Elektrikoa eta Elektronikoa
    The use of defected ground structures (DGS) is being intensively explored by the microwave filter designer community. The DGSs are one possible implementation of a 1D Photonic Band Gap (1D-PBG) where some defect structures are patterned on the ground plane of a microstrip circuit. In this paper, the relation between the behaviour of the DGS structures and the classical microwave filter design theory is established. In particular, a simple model procedure based on the classical microwave filter design theory by using DGS structures is presented. In order to illustrate the method, two low-pass filters are designed, fabricated and measured.

    Diseño de filtros banda rechazada usando Defected Ground Structures (DGS)
    (2003) Garde Irigoyen, Ieltxu Aitor; Río Bocio, Carlos del; Ingeniería Eléctrica y Electrónica; Ingeniaritza Elektrikoa eta Elektronikoa
    In this paper a type of Defected Ground Structure (DGS) is studied and used to implement filters in microstrip technology. It is first demonstrated that the main parameter which controls its operation is the external perimeter, and that the periodicity is no longer required in order to achieve a filtering response. These two important conclusions are used to fabricate filters comparable to others already made by other authors, which are constrained to equal unit cells and a periodic distribution of them.
