1. An electronic device comprising:
a printed circuit board (PCB);
a metal frame comprising a section;
a slot antenna, wherein the slot antenna comprises:
a slot between the PCB and the section of the metal frame, wherein the slot comprises:
two ends that are grounded;
a first side edge comprised of a side edge part of the PCB; and
a second side edge comprised of the section, wherein the second side edge comprises:
a first part; and
a second part;
a slit on the second side edge, wherein the first part is on a first side of the slit and the second part is on a second side of the slit;
a first feeding point on the first part;
a second feeding point on the second part;
a feeding source comprising a positive electrode coupled to the first feeding point and a negative electrode coupled to the second feeding point; and
a bridge structure comprising:
a first end coupled to the first part; and
a second end coupled to the second part; and
