A new type of directional dual‐band antenna is developed for 2.4/5 GHz wireless applications. The dual‐band antenna consists of a longer dipole for the lower band and a pair of shorter dipoles for the upper band. A simple coupling microstrip line is employed to excite the dipoles. Both the dual‐band antenna and the feeding microstrip line are printed on the same substrate, leading to a fully planar structure. The dual‐band planar antenna achieves a desirable directional radiation pattern with an antenna gain of near 8 dBi for the lower band and 9–10 dBi for the upper band. A comprehensive analysis and design for the development of the directional dual‐band antenna is presented.
