In this letter, a method to design wideband Fabry–Perot resonator (FPR) antennas is presented. The structure employs closely spaced truncated thin dielectric slabs as a partial reflecting surface (PRS). An analytical design process based on transmission line theory is proposed. The criterion for wideband FPR antennas is generalized for a highly truncated PRS, i.e., the PRS only needs to exhibit a resonance at the center frequency of the band. Based on the finding, a compact FPR antenna is optimized and experimentally validated with a wide 3 dB gain bandwidth of about 86% and maximum realized gain of 14.2 dBi.
