Fig. 1. Topology of the substrate integrated waveguide. In this paper, we will propose, design of waveguide slots array antennas based on the SIW technology, the array consists of two longitudinal slots and it is match terminated. Firstly, we give the design equations for tapered microstrip-SIW transitions.

A Frequency-Scanning Substrate-Integrated-Wave- guide ... the SIW. Longitudinal slots elements were chosen for this design to minimize cross-polar radiation [9]. By contrast, other researchers have used tilted slots [3] or bowtie slots [6], which result in substantial cross-polarization and degraded sidelobe levels. A Frequency-Scanning Substrate-Integrated-Wave- ANALYSIS AND DESIGN OF SLOTTED SUBSTRATE INTEGRATED ... This thesis presents novel traveling wave conformal shunt slot arrays on cylindrical substrate integrated waveguide (CSIW) placed on a cylindrical surface in the circumferential direction at K-band. Mutual couplings of longitudinal slots on broad wall of CSIW are formulated and active admittance formulas of the slots are derived Compact Two-Layer Slot Array Antenna for K-Band ... A novel two-layer slot array antenna based on substrate integrated waveguide (SIW) technology was designed and simulated. Unlike already reported SIW slot arrays, the present design achieves considerable reduction in size by using a feed waveguide placed underneath the slot array and coupled through slanted slots to branches of the array.

Feb 13, 2017 · The lecture presents the results of an investigation of leaky wave antennas designed on a substrate integrated waveguide. The interest is given to three antenna types: an antenna radiating from a wide longitudinal slot etched in the top waveguide wall, a SIW CRLH leaky wave antenna, and a dual band SIW CRLH leaky wave antenna.

Design and implementation of low sidelobe substrate integrated waveguide longitudinal slot array antennas

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. Transitions from SIW to Various Transmission Lines for ... insertion loss is poor. Longitudinal slots are also used to couple energy from SIW to the waveguide. When the substrate with a longitudinal slot etched on the broad wall of the SIW is surface mounted to the standard flange of the waveguide, it acts as the window to transfer energy [7], however, the design suffers from narrow bandwidth of 800MHz.
