Abstract: An antenna design solution is provided. A metal frame and a PCB ground layer of an electronic device are used to form a slot. Through symmetric feeding and anti-symmetric feeding, the slot can be excited to generate two slot antenna patterns: a CM slot antenna pattern and a DM slot antenna pattern. In addition, the two slot antenna patterns share a same slot antenna radiator.
