Longitudinal slots on substrate integrated waveguide

a longitudinal slotted array antenna design on substrate integrated ...

rectangular dielectric-filled waveguide that is synthesized in a planar substrate with arrays of metallic vias or slots in order to realize bilateral edge walls. Integrated transitions can be designed on the same substrate compatible with planar structures such as microstrip and coplanar waveguide [14, 15]. SIW structure can be Dual Band and Dual Polarized Substrate Integrated Waveguide ... longitudinal and transverse slots on the broad wall of the substrate integrated waveguide. The two resonances are completely apart in a low cross polarization level at both sets. antenna has a minimum radiation efficiency of 80% in both bands. KEYWORDS: Dual band, Dual polarized, Slot antenna, Substrate integrated waveguide I. INTRODUCTION Leaky Wave Antennas Designed on a Substrate Integrated Waveguide of leaky wave antennas designed on a substrate integrated waveguide. The antennas are of the following types: antenna radiating from a slot in the top waveguide wall, CRLH and dual band CRLH leaky wave antennas. The substrate integrated waveguide can easily be integrated with planar microwave circuits. Logarithmic Slots Antennas Using Substrate Integrated Waveguide

Abstract: By etching longitudinal slots on the top metallic surface of the substrate integrated waveguide (SIW), an integrated slot-array antenna is proposed in this letter. The whole antenna and feeding system are fabricated on a single substrate, which takes the advantage of small size, low profile, and low cost, etc. Improved Design of Low Sidelobe Substrate Integrated ...

In this work, substrate integrated waveguide (SIW) slot antennas are proposed for 60-GHz channel characterization. The antennas consist of a group of three longitudinal slots placed in one or both broad walls of an SIW. Depending on the placement of the slot group, the SIW slot antenna achieves a directional or omnidirectional radiation pattern. Current and Future Research Trends in Substrate Integrated

Optimum Design of SIW Longitudinal Slot Array Antennas with ... Waveguide slot array antennas have many applications in communication and radar systems [1-2], due to their significant advantages such as: high efficiency, high gain, mechanical strength, and the absence of spurious radiations from the feed system. The most common configuration for slot array antennas is the longitudinal slots due to
