Title: | Control of inter-resonator coupling using defected ground structure lattice | Authors: | Radonić, Vasa Crnojević-Bengin, Vesna |
Issue Date: | Mar-2015 | Journal: | Electronics Letters | Abstract: | © The Institution of Engineering and Technology 2015. A novel method to control inter-resonator coupling using the defected ground structure lattice (DGS-L) is proposed. The influence of the geometrical parameters of the lattice on the intensity of the coupling between ring resonators is analysed in detail. It is shown that the inter-resonator coupling can be increased significantly by using DGS-L, which leads to the miniaturisation of wideband bandpass filters designed using standard filter design theory. To illustrate the effect of incorporating the proposed DGS-L, the direct-coupled bandpass filter of the third order has been designed, fabricated and measured. The filter exhibits ~40% wider bandwidth compared with the same filter designed without the use of DGS-L, while its footprint remains unchanged. | URI: | https://open.uns.ac.rs/handle/123456789/18045 | ISSN: | 0013-5194 | DOI: | 10.1049/el.2014.4177 (BISIS)105629 |
