摘要： A dual-band Wi-Fi antenna structure includes a metallic middle frame of a casing of a handheld electronic device, a grounding plane received in the middle frame, an antenna body connected to the grounding plane, and an adjusting element. The grounding plane defines a rectangular recess in a corner thereof. The antenna body has a radiation patch having a part located over the recess. The adjusting element is located in the recess. An effective length of the recess is adjustable by adjusting a parameter of the adjusting element, which is a coefficient of self-inductance when the adjusting element is an adjustable inductor. By adjusting the effective length of the recess, a resonant frequency of the antenna structure at a low frequency band is adjustable, while a resonant frequency thereof at a high frequency band is not altered.
