Patent attributes
A loop antenna which has a signal input/output wire, a first conductor, an upper conductor, an upper conductor, a second conductor, a first lower conductor, and a second lower conductor sequentially connected. The loop antenna further has a first grounding via, and a lower end of the first grounding via is connected to a first grounding layer, and an upper end of the first grounding via is disposed between and connecting the first lower conductor and the second lower conductor, wherein a first end of the second lower conductor is connected to the upper end of the first grounding via, and a second end of the second lower conductor is connected to the first conductor. A second grounding layer and the combination of the signal input/output wire, the first lower conductor, and the second lower conductor are disposed on the same layer disconnectedly.
