Substrate-integrated waveguides (SIWs) maintain the advantages of planar circuits (low
loss, low profile, easy manufacturing, and integration in a planar circuit board) and improve …

Substrate-integrated circuits (SICs)[1] have attracted much attention in the last several years
because of their great potential. The first implementation of the concept can be found in [2] …

Although several bandpass filters have been designed in the recently proposed empty
substrate integrated waveguide (ESIW) technology to improve the quality factor and reduce …

The empty substrate integrated waveguide (ESIW) technology is recently receiving special
attention, since it preserves the many advantages of SIW circuits but provides an enhanced …

A Y-junction circulator based on empty substrate integrated coaxial line (ESICL) technology
is proposed in this paper. As ESICL is a novel transmission line, many of the common …

The empty substrate integrated waveguide (ESIW) presents the same advantages as the
substrate integrated waveguide (SIW): low cost, low profile, and easy integration, but with …

The Empty Substrate Integrated Waveguides (ESIW) maintain the advantages of the
Substrate Integrated waveguide (SIW)(ie low-volume, low profile, lightweight, easy …

In the last years a great number of substrate-integrated circuits has been developed. These
circuits are a compromise between the advantages of waveguides: high-quality factor and …

Empty substrate integrated waveguide (ESIW) devices can provide high quality and
completely integrated devices, but they are usually larger than the same ones implemented …

Substrate integrated circuits (SIC) have attracted much attention in the last years because of
their great potential of low cost, easy manufacturing, integration in a circuit board, and higher …
