A simple technique for frequency-static multi-notch/transmission-zero (TZ) creation in RF filters with single- and dual-band bandpass transfer functions is presented. It is based on the direct connection of two identical inline filtering units withou

A class of dielectric filtering inverted-L antenna with reflective- and quasi-reflectionless-type radiation nulls is proposed to achieve wideband or dual-band operation. To this aim, a dual-function dissipative branch is exploited, which is in-parall

This work presents a design technique to implement miniaturized cross-coupled bandpass filters in inline physical configurations based on triple-mode resonators. Triple-mode resonances are obtained by using integrated coaxial-waveguide cavity resonat

This paper presents a novel method for cross-band scattering cancelation in closely-spaced antennas inspired by absorptive/reflectionless filtering principles. Prior-art approaches that combine a bandpass-filter (BPF) unit and an antenna in multiple-

In this paper, two types (i.e., type-A and type-B) of hybrid microstrip/defected ground structure (DGS) cells are proposed for passive circuit implementation with ultra-wide stopband. Both cells consist of the stepped-impedance DGS and embedded folde

The influence of the stiffness of piers, pylons and deck in the behaviour of multi-span cable-stayed bridges under alternate live loads is analysed. The variation of these parameters is discussed considering both a harp cable system and a fan cable s
