“…The resonators are designed with Dumbbell structures due to their smaller etching area and reduced ripple heights with preferred insertion loss within the passband (18). The bandpass filter is implemented by cascading two Stub Loaded Cross Dumbell Shape Resonators (SLCDSR), as shown in Figure 2.…”

Identification of a suitable substrate is a critical parameter in the design of microstrip bandpass filters. In this work, the performance of an Ultra Wideband (UWB) bandpass filter based on Electromagnetic Bandgap (EBG) resonators are designed, fabricated, and analyzed. Printed Circuit Board (PCB) with suitable dielectric substrates are used extensively to develop microstrip lines. The filter is fabricated using RT Duroid substrate material and compared with FR4 and Alumina dielectric substrates and the performance results show that the best result is obtained with RT Duroid.

“…Several works in the literature used EBG to suppress harmonics or spurious, in microstrip antennas 8‐11 or even to improve the performance of microstrip filters, through the suppression of spurious 12‐14 . However, it is not known to the authors, the use of EBG for suppression or reduction of higher‐order modes in FSS.…”

In this article, the authors present a proposal for the application of electromagnetic bandgap (EBG) for suppression of higher-order modes in frequency selective surfaces (FSS), not yet studied in the literature. The study consists of an application of a rectangular periodic array of circular holes in FSS dielectric substrate to create rejection bands and suppress specific resonant frequency modes. We built four prototypes and compared measured results with simulated results obtained with ANSYS HFSS and it completes the proposed equivalent circuit validation. Simulations and measurements show suppression levels up to 10 dB. A good agreement between the results is observed.
