This letter presents a novel dual-band patch antenna developed by combining the folded-patch and U-slot techniques. The electrical length of the antenna is 0.147 wavelengths at the center frequency of the lower band. The lower band of the antenna ranges from 2.400 to 2.480 GHz, while the upper band covers both frequency bands from 5.150 to 5.350 GHz and 5.725 to 5.875 GHz with an average gain of 2 dBi. It is suitable for short-range wireless applications.
