This paper presents a compact, triple-port, millimeter-wave (mm-wave) substrate-integrated waveguide (SIW) based annular slot antenna. The presented antenna was fabricated on single dielectric layer, 30 mil TLY-5 substrate with standard PCB process. Measurement results show that, the proposed can achieve better than dB isolation between ports at 28 GHz, thanks to carefully tuned distances and &...

Some interesting results are presented in this paper by investigating the characteristics of square high-order mode cavities. Based on the standard printed circuit board (PCB) process and the substrate integrated waveguide (SIW) technology, two different square cavities which exhibit dual-mode filtering response are studied and implemented. Their bandwidths can be controlled by adjusting the ei...

Microwave resonators working as sensors can detect only a single analyte at a time. To address this issue, a TE20-mode substrate-integrated waveguide (SIW) resonator is exploited, owing to its two distinct regions of high-intensity electric fields, which can be manipulated by loading two chemicals. Two microfluidic channels with unequal fluid-carrying capacities, engraved in a polydimethylsilox...

A new wideband Wilkinson Power Divider which use the nonuniform substrate integrated waveguide (NSIW) method is presented in this paper. This structure utilizes NSIWs instead of the uniform quarter wavelength SIWs in conventional Wilkinson power divider. The proposed structure is analyzed by odd and even mode analysis. The proper NSIW section widths can be extracted by using even mode while the...

This letter presents a substrate-integrated waveguide (SIW) antenna for CubeSat applications. The compact structure utilizes middle-point feeding and shorting walls to achieve broadside radiation in the far-field at two distinct frequencies. In particular, this dual-frequency behavior is related transition from dominant leaky wave (LW) on aperture lower frequencies more hybrid (at higher freque...
