Abstract—In this paper, the design of slots array antennas based on Substrate Integrated waveguide (SIW) has been analyzed and simulated. A waveguide slot antenna has a vertical row of slots along the length of a vertical waveguide, with the array of slots increasing the gain by flattening the vertical beam.

In [2], the excellent dual and linearly polarized slot array antenna was proposed using a broad wall shunt slot array and narrow wall series slot array combination within a common aperture to eliminate the grating lobes. Non-Resonant Slotted Waveguide Antenna Design Method
In this paper, several configurations of Ka-band SIW-fed slot array antenna have been investigated. At first, a 1*4 corporate SIW feeding network integrated of Y- and T-junction power divider operating in 30 GHz was designed and simulated in order to provide a proper feeding network intended for the design of 4*4 and 4*8 antenna arrays.
