Abstract
This paper presents a design and measurement of symmetric bidirectional pattern antenna implemented by using a probe-fed open-ended rectangular waveguide (OERW) vertically attached with four-stacked-coupling-aperture (FSCA). For the OERW without FSCA, it provides asymmetric beam in forwards and backwards directions. With the effect of FSCA, that asymmetry is amended to be symmetry, and propagates the WLAN frequency band of 2.4–2.5 GHz with the return loss better than 10 dB, and maximum gain of 7.04 dBi. A prototype antenna was fabricated and measured. Obviously, the preliminary measured results are very reassuring, and reasonably in good agreement with simulation results.
