A dual-band antenna includes a first conductive portion, a ground layer, a ground portion, a second conductive portion and a third conductive portion. The first conductive portion has a resonant cavity. The ground portion extends from the ground layer toward the first conductive portion. The second conductive portion extends from the ground layer toward the first conductive portion. The third conductive portion extends from the ground layer toward the first conductive portion. The second conductive portion and the third conductive portion are disposed symmetrically with respect to the ground portion.

A wireless charging circuit includes a substrate. The first surface of the substrate includes a first metal wire, which is spirally disposed on the first surface. A second metal wire is disposed on the second surface of the substrate. An end of the second metal wire is electrically connected to an end of the first metal wire. The second metal wire further has a first extending portion on the second surface; wherein the first extending portion is corresponding to the first metal wire and the length of the first extending portion is smaller than a half of that of the first metal wire.

Wireless charging circuit

A monopole slot antenna structure including a dielectric substrate, a monopole slot antenna and a feed element is provided. The monopole slot antenna is disposed on one side of the dielectric substrate and has a slot including a first slot section, a tuning slot section and a second slot section. One end of the first slot section is located at one edge of the monopole slot antenna with the other end of the first slot section being extended towards internal portions of the monopole slot antenna and being connected to the tuning slot section. One end of the second slot section is connected to the tuning slot section with the other end of the second slot section being extended away from the first slot section. The feed element is disposed correspondingly to the second slot section, and excites the monopole slot antenna to generate two operating frequency bands.
