In this article, a conformal leaky wave antenna with a substrate-integrated waveguide (SIW) structure on a new unit cell substrate is presented. The use of this new method eliminates the main problem of this type of antenna, which is the existence of a stop band (OSB), and enables the antenna to radiate in Broadside as well. In this article, after introducing the new unit cell, a flat leaky wave antenna with an integrated waveguide structure under the layer, which is able to continuously scan from -76.6 to +27 degrees by changing the feeding frequency, was designed and investigated. At the end, the proposed flat antenna is adapted on the surface of a cylinder with a radius of 425 mm. A conformal leaky wave antenna is able to continuously scan from -43 to +37 degrees by changing the feeding frequency. As a result, a scan with circular polarization from negative to positive angles, which also includes broadside radiation, has been obtained.
