This paper presents a design of uni-directional beam antenna implemented by a probe-feed open waveguide with two-stacked-coupling aperture. In the analysis, the probe-feed open waveguide without and with stacked-coupling-aperture are demonstrated. Apparently, this antenna operates the WLAN frequency band of 2.4?2.5 GHz with the magnitude of |S11| lower than -10 dB. The simulated half-power beamwidths in both the E- and H-planes are equal 70? with the maximum gain of 7.1 dBi.
