  • Patent number: 11545757
    Abstract: A single-layer substrate integrated directive broadside beam leaky-wave antenna is provided. Opposite ends of a leaky-wave structure are fed with anti-phase versions of a common signal, resulting in broadside frequencies being set apart from the open stopband. To achieve this, the common signal can be split into two equal length paths, one including a perfect electrical conductor (PEC) reflector and the other including a perfect magnetic conductor (PMC) reflector. Alternatively, the common signal can be split into two paths which differ in length by a half wavelength. A power splitter and feed horns can be used in the respective paths. The leaky-wave structure may have transverse slots which increase in width toward a midpoint of the structure. The antenna can be formed in a single planar portion of a lithographic structure, for example by patterning an upper conductive layer thereof.
