This article presents a modular substrate-integrated waveguide (SIW) antenna array based on H-plane aperture structures for Ka-band. The unitary antenna is based on a SIW aperture antenna with an improved H-plane radiation pattern by means of the implementation of metallic vias in the wave propagation along the H-plane antenna. The inner metallic vias are introduced to form four diffe... https://www.bekindtopets.com/flash-offer-Freetress-Fullcap-Drawstring-Wig-CRETA-GIRL-clearance/
