“…Recently, EBGs and PBGs are of great interest due to their extraordinary properties and potential applications e.g., filters, polarizers, substrates for radiating elements, or optical switches [2][3][4][5][6][7][8][9][10][11][12][13][14][15]. FSSs find also application in polarizers and polarization rotators to change the polarization state of an electromagnetic wave [16,17].…”

Abstract-In the paper, the analysis of electromagnetic wave scattering from multilayered frequency selective surfaces is presented. The surface is composed of periodically arranged posts with irregular shapes. The multimodal scattering matrix of such structure is derived and the transmission and reflection characteristic for the structure with arbitrary plane wave illumination are calculated. The exact fullwave theory based on the hybrid approach employing mode-matching method and finite-difference frequency-domain (FDFD) technique is applied to develop an efficient theory to analyze such structures. The validity and accuracy of the approach are verified by comparing the results with those obtained from alternative methods and own measurements of manufactured periodic structures.

“…Several types of dual-mode microstrip resonators with perturbation element have been investigated, including EBG-based resonator [6], ring resonator [7], square-ring resonator [8], multi-arc resonators [9]. The dual-mode here means two degenerate resonant modes of the aforementioned geometrically symmetrical resonator, and the two degenerate resonant modes may be split by introducing a perturbation element in a resonator.…”

Abstract-A compact dual-mode open stub-loaded resonator and bandpass filter (BPF) is proposed in this paper. The resonator, which is formed by attaching a disc-shaped open stub and circular open stubs in pairs to a high impedance microstrip line, generates two operating modes in the desired band, and the even-mode resonance frequency can be flexibly controlled by the disc-shaped open stub at central plane, whereas the odd-mode one is fixed. The four transmission zeros are created to sharpen the rejection skirt, suppress two high harmonic resonant modes and deepen upper-stopband, respectively. Experimental results of the dual-mode filter which incorporates this resonator with parallel-coupled feed line with tuning stub at 5.8 GHz show good agreement with the simulated ones. The size for the resonator is only 4.7 × 3.4 mm (0.29λ g × 0.21λ g in which λ g is the guided wavelength of 50 Ω microstrip at 5.8 GHz).

Abstract-For the application of K connector (K103F) at Ka-band, many problems exist, due to the complex method of installation. In this paper, the test fixture is simplified, and the performance of this section is improved with the Electromagnetic bandgap (EBG) structure. Simulation results are presented for the connection structure with EBG; plots of the input reflection of geometrical and physical parameters are reported and commented on.
