Abstract
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 behavior due to avoidance of dielectric filling. Many circuits have been designed in the ESIW technology, including several filters with different performances. The next challenge is to achieve the maximum possible compactness degree for these circuits. In this paper, we present the design of a multilayer empty substrate integrated filter with the same performance as if it were manufactured in a single layer but significantly increasing its compactness and mechanical resistance.
