Abstract
An antenna structure includes a metallic member, a feed portion, and a coupling resistor. The metallic member defines a slot, a first gap, a second gap, and a third gap. The first gap and the second gap are connected with the slot and divide with the slot the metallic member into a first portion and a second portion. The second portion is grounded. The third gap is defined on the first portion and connected with the slot. The first portion is divided into a radiating portion and a coupling portion by the third gap. The coupling portion is spaced apart from the radiating portion. The feed portion is electrically connected to the radiating portion, and the coupling portion is grounded through the coupling resistor.
