Design Formulas for Planar Fabry–Pérot Cavity Antennas Formed ... Planar Fabry–Pérot-cavity (FPC) antennas, a class of leaky-wave (LW) antennas [1]–[22], are known as a promising solution to produce highly efficient directive radiation using a single feed point. This antenna consists of a grounded cavity formed by using a partially reflective-surface (PRS) superstrate. In [9]–[13], [19], W1GHZAntenna Book W1GHZ
