Substrate integrated Waveguide – Base for Leaky Wave Antennas ... 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.

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.

Substrate integrated waveguide (SIW) is a promising technology for planar antennas arrays in which antipodal linear tapered slot antennas (ALTSAs) are fed by a network of SIW power dividers [1] – [3]. These dividers have first been reported in [4], and Y- and T-junction SIW power dividers integrated...
