In this paper, the authors present the results of an investigation of a new version of a leaky wave antenna that is based on a Substrate Integrated Waveguide (SIW). The structure of SIW is composed of two rows of cylinders between metal plates; it can be easily produced by the standard method "PCB circuit" or LTCC method, the antenna is designed so that it can radiate in C-band. The direction of the main lobe of the antenna radiation pattern can be steered by changing the frequency in the band from backward direction to forward direction; the effect of increasing the number of slot arrays has also been analyzed to study the effect on radiation patterns.
