A small EBG resonator antenna (1.62lambda0times1.62times0timeslambda0/4 in size) with specially-located PEC sidewalls to close the resonant cavity is proposed to achieve maximum directivity. An in-phase highly-reflecting surface is installed a quarter-wavelength above the PEC ground plane. For this small EBG resonator antenna, 13.5 dBi measured directivity and 11 dBi peak gain are obtained at 11.6 GHz.
