planar slot antenna using Substrate Integrated Waveguide technology (SIW) is proposed in this paper. SIW has all the advantages required for a small size antenna package: Lowcost, high-performance and ease of integration. The SIW antenna with tapered microstrip-SIW transitions are integrated and synthesized on a single substrate. This structure is designed with Finite Element Method (FEM) using...

In this brief, a wide stopband bandpass filter is designed based on the substrate integrated waveguide (SIW) coupling with complementary split ring resonators (CSRRs) and defect ground structure resonators. The proposed exhibits excellent roll-off characteristics single SIW resonator cavity. A simple capacitive slot line also to improve flatness in passband. order verify feasibility of scheme, ...

circularly-polarized antenna is built based on a new siw (substrate integrated waveguide)structure which contains cavity-backed resonator and a conventional polarized ring with twosquare slits in inner and outer ring that differ 90° at position and is proposed for right-handedcircular polarization (rhcp) and fabricated in two separate layers. a broadband impedancebandwidth of 13.9% and a rhcp a...

A wideband circularly polarized antenna based on the substrate integrated waveguide (SIW) is investigated and presented for mobile satellite applications. Initially, a rectangular-slot etched top layer of SIW cavity. truncated patch from one corner (top left) loaded inside slot to obtain two pairs orthogonal degenerate modes TE130/TE310 TE230/TE320. This truncated-corner helps bring closer circ...

A novel triple-band filter using triple-mode substrate integrated waveguide (SIW) resonator is presented in this paper. The proposed resonator consists of a square cavity with two additional metallic vias that split the first pair of degenerate modes (TE201 and TE102) at the diagonal of the cavity. Triple-band response is achieved by TE101, TE201 and TE102. The center frequencies of the first b...
