Improved Low Reflection Transition From Microstrip Line to Empty Substrate-Integrated Waveguide [PDF]
IEEE Microwave and Wireless Components Letters, 2017 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 the quality factor of filter resonators. Empty substrate-integrated waveguides (ESIWs) substantially reduce the insertion losses, because waves propagate through air instead

The empty substrate-integrated waveguide (SIW) (ESIW) is an evolution of the SIW. Just as the SIW, the ESIW is of low cost and low profile, and can be integrated into a printed circuit board, but the losses in the ESIW are lower than in those in the SIW thanks to the removal of the dielectric material, which results in ESIW devices with performances ...

Empty Substrate Integrated Waveguide Antenna Array
2018 IEEE International Symposium on Antennas and Propagation & USNC/URSI National Radio Science Meeting, 2018An Empty Substrate Integrated Waveguide (ESIW)antenna array concept is presented. The ESIW provides an array feed network which offers low loss, low cost, and low profile, in addition to being able to integrate the antenna with other electronics into a single printed circuit board.

Design of Half Power Divider at Ku-band using Empty Substrate Integrated Waveguide
2020 IEEE MTT-S Latin America Microwave Conference (LAMC 2020), 2021This paper presents a half power divider operating at Ku-band which is designed using concept of Empty SIW. For easy connectivity with other planar microwave devices and circuits, the micro strip line to HSIW transition was implemented, with section of ESIW expanded at discontinuity interface, to reduce radiation and leakage effects and provide ...

Experimental study in Ku-band of the propagation inside Empty Substrate Integrated Waveguides
2016 46th European Microwave Conference (EuMC), 2016In 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 low losses, and the advantages of planar circuits: low-cost and easy compact integration.

A Compact and Wideband SMA Connector to Empty Substrate Integrated Waveguide (ESIW) Transition
2015 IEEE MTT-S International Microwave and RF Conference (IMaRC), 2015In this paper, a novel excitation technique by a commercially available SMA connector is presented for the empty substrate integrated waveguide (ESIW). The SMA connector is directly connected to one end of the ESIW. A prototype back-to-back transition is designed and fabricated for X-band operation.
