A simple and compact directional dual‐band semi‐circular inverted‐F antenna for wireless local area network applications is reported. Two pairs of semi‐circular slots as well as a pair of arms are employed to generate the dual resonances in the 2.4–2.48 and 5.2–5.8 GHz bands. The measured results show that the proposed antenna can provide two 10 dB impedance bandwidths of 160 MHz (2.40–2.56 GHz) and 900 MHz (4.95–5.85 GHz). Nearly constant directivities (about 4.7 dBi) are observed in the lower band, while directivities in the upper band vary between 6.3 and 8.6 dBi.
