Electronic device

An electronic device, comprising:

• a first body having a conductive housing, the conductive housing having a first closed slot, a second closed slot, a feed point and a ground point;
• and
• a feed device disposed in the first body, the feed device including:
• a circuit substrate, having a first surface, a second surface, a plurality of first conductive holes and a plurality of second conductive holes, wherein the first surface faces the conductive housing and is opposite to the second surface;
• a feed portion and a ground portion, disposed on the second surface;
• and
• a first connection portion and a second connection portion disposed on the first surface, wherein the feed portion is electrically connected to the feed point through the plurality of first conductive holes and the first connection portion of the circuit substrate, and the ground portion is electrically connected to the ground point through the plurality of second conductive holes and the second connection portion of the circuit substrate,
• wherein the feed device and the conductive housing form an antenna, the antenna operates in a first band through a first path formed by the first closed slot and operates in a second band through a second path formed by the second closed slot,
• wherein the feed point is disposed between the first closed slot and the second closed slot, and the feed point and the ground point are disposed on two sides of the second closed slot.
