In recent years, with the rapid development of integrated circuits, filtering antenna (FA) circuit substrate waveguide (SIW) has attracted widespread attention in wireless communications. Numerous structures have been proposed to improve performance SIW FA. Hence, this paper presents and miniaturization trend FA, briefly introduces structure historical terms mode, multi-mode cavities incomplete...

Substrate-integrated-waveguide (SIW) technology can eliminate the limitations associated with conventional rectangular waveguides, i.e., bulky structures and production complexity at higher frequencies. Moreover, SIW replaces microstrip eliminating drawback of excessive radiation leakage power dividers are key elements in antenna array synthesis. A divider’s design procedures more complicated t...

A guided-mode-resonance device for both narrow-band retroreflection and waveguide input coupling was designed fabricated operation wavelength of 1550 nm. It consists a focusing grating coupler (FGC) integrated in cavity resonator constructed by pair distributed Bragg reflectors (DBRs) on reflection substrate. The size the FGC 31 × 20 μm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:...

To meet the packaging requirements of terahertz (THz) communication systems, a microstrip line (MSL) to rectangular waveguide (RWG) transition is proposed in this paper. In transition, MSL connected corrugated substrate integrated (CSIW) by tapered for quasi-TEM TE10-like mode conversion on substrate, which requires no via holes or shaped dielectric, and easy process THz bands. Then, CSIW strai...

A substrate integrated waveguide (SIW) bandpass filter with adjustable out of band transmission zeros based on through-silicon via (TSV) technology is proposed. The single-cavity degenerate mode separated by the metal via-hole and defect grounding structure, which coupled other cavities to generate positions increase roll-off rate. results show that, center frequency 148GHz, bandwidth 6.5GHz, m...

A broadband rectangular waveguide to substrate integrated power divider for hybrid beam forming networks is presented. Rectangular symmetric E-plane irises are used realize a multi-section matching network. circuit and full-wave design procedure described adopted synthesize three with one, two, irises, progressively increasing the bandwidth exceeding state of art in last two cases. Three proof-...
