Tunable Substrate Integrated Waveguide Diplexer With High Isolation and Wide Stopband
IEEE Microwave and Wireless Components Letters, 2019A tunable multilayer diplexer using substrate integrated waveguide (SIW) technology is proposed in this letter. A multilayer design is chosen to easily control the electric and magnetic coupling through circular slots in order to achieve a wide-stopband ...

Slow-Wave Substrate Integrated Waveguide
IEEE Transactions on Microwave Theory and Techniques, 2014This paper describes a new concept of substrate integrated waveguide (SIW): a slow-wave substrate integrated waveguide (SW-SIW). Compared to a conventional SIW, the proposed topology requires a double-layer substrate with a bottom layer including internal metallized via-holes connected to the bottom conductive plane. The slow-wave effect is obtained by

A Compact Wideband Phase Shifter Using Slotted Substrate Integrated Waveguide
IEEE Microwave and Wireless Components Letters, 2019A compact phase shifter using substrate integrated waveguide (SIW) with two slots is proposed in this letter. The wideband phase shift is mainly caused by the opposite phase shift slopes produced by the slots and the microstrip delay lines over a wide ...

On the losses in substrate-integrated waveguides and cavities
International Journal of Microwave and Wireless Technologies, 2009This paper presents a study of losses in substrate-integrated waveguides (SIWs) and cavities. Three mechanisms of losses are considered and separately investigated, namely radiation leakage, ohmic loss, and dielectric loss. A systematic comparison of waveguides with different geometry, operating at different frequencies, is reported. This study permits

Slots on cylindrical substrate integrated waveguide
Proceedings of the 2012 IEEE International Symposium on Antennas and Propagation, 2012Longitudinal slots and coupling between slots placed on the broad wall of a cylindrical substrate integrated waveguide (SIW) are modeled and characterized in order to design a slotted cylindrical SIW array. Characteristics of slot on the SIW bended on a cylindrical surface and effects of radius of curvature to the slot and mutual coupling ...

Narrowband Substrate Integrated Waveguide Isolators
IEEE Microwave and Wireless Components Letters, 2014In this letter, two types of X-band ferrite-loaded isolators are proposed based on the substrate integrated waveguide (SIW) technology. First, a full-height E-plane ferrite slab is used to construct low-loss and high-isolation SIW isolators. The insertion loss is less than 2.2 dB and the isolation coefficient is larger than 30 dB within 400 MHz ...

60GHz Substrate Integrated Waveguide Balun
2019 IEEE Conference on Antenna Measurements & Applications (CAMA), 2019In this paper, we design a balun that operates at 60GHz. The proposed balun is based on a substrate integrated waveguide (SIW) structure that can reduce losses in high frequency bands. A single-ended signal is divided by 3-dB power divider, and then differential signals are generated by inverting the phase. In simulation, the amplitudes of differential

A Sidelobe Level Reduction Method for mm-Wave Substrate Integrated Waveguide Slot Array Antenna
IEEE Antennas and Wireless Propagation Letters, 2019A new method of sidelobe level (SLL) reduction for a substrate integrated waveguide (SIW) slot array antenna is presented. In this method, amplitude distribution is assigned to the slots by tapering the SIW width.
