Journal ArticleDOI
Analytical Wideband Model for Strip/Slit Gratings Loaded With Dielectric Slabs
TL;DR: In this paper, the transmission and reflection properties of planar 1-D distributions of metal strips or slits made in thin metal screens have been investigated over a wide frequency band, from the long wavelength limit to the grating lobes operation.
Journal ArticleDOI
Analytical Multimodal Network Approach for 2-D Arrays of Planar Patches/Apertures Embedded in a Layered Medium
TL;DR: The key advantages of the reported multimodal network representation are its analytical nature, its extremely low-computational cost and that the physical phenomena involved in the scattering can be easily understood in terms of transmission line and lumped circuital reasonings.
Journal ArticleDOI
Application of Total Least Squares to the Derivation of Closed-Form Green's Functions for Planar Layered Media
TL;DR: In this article, the spectral-domain Green's functions are approximated by an asymptotic term plus a ratio of two polynomials, the coefficients of these two coefficients being determined via the method of total least squares.
Journal ArticleDOI
Differential Bandpass Filter With Common-Mode Suppression Based on Open Split Ring Resonators and Open Complementary Split Ring Resonators
Paris Velez,Jordi Naqui,Armando Fernandez-Prieto,Miguel Duran-Sindreu,Jordi Bonache,Jesus Martel,Francisco Medina,Ferran Martin +7 more
TL;DR: Differential (balanced) microstrip bandpass filters (BPFs) implemented by combining open split ring resonators (OSRRs) and open complementary split ring Resonators (OCSRRs) are proposed in this paper.
Journal ArticleDOI
Parallel coupled microstrip filters with floating ground-plane conductor for spurious-band suppression
TL;DR: In this paper, a floating strip conductor printed on the backside of the substrate is used to suppress the spurious transmission band appearing at twice the central frequency of coupled-line microstrip filters.
