A review of substrate integrated waveguide (SIW) components designed for the use in beam-
forming networks working in X-Band is presented. The proposed devices are four-port and …

In this article, empty substrate integrated waveguides (ESIW) technology is applied to design
long slot leaky-wave antennas (LWAs). First, a uniform-aperture structure is presented and …

Efficient wide-band transitions play a critical role in integrating substrate-integrated
waveguide (SIW) and air-filled substrate-integrated waveguide (AFSIW) systems with …

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

Despite extensive research on integrating Substrate Integrated Waveguide (SIW)
technologies with conventional transmission technologies such as Microstrip Transmission …

Substrate Integrated Waveguides (HSIWs), demonstrated in the nominal frequency from 21 …

This paper presents for the first time a compact wideband bandpass filter in groove gap
waveguide (GGW) technology. The structure is obtained by including metallic pins along the …

Empty substrate integrated waveguide (ESIW) technology preserves the many advantages
of the SIW, such as low cost, low profile, or integration in a printed circuit board. But, since …

This article reports the design of high-selectivity tunable bandpass filters with constant
absolute bandwidth (CABW) using dual-mode (DM) substrate-integrated-waveguide (SIW) …

This letter presents a microstrip patch antenna array fed with a low-loss and highly efficient
feeding structure called empty substrate-integrated waveguide (ESIW). The proposed …
