Abstract

A portable electronic device comprises a main body and an antenna. The main body comprises a first casing, a second casing and a hinge, with the hinge connecting the first casing and the second casing so as to allow the first casing to be flipped relatively to the second casing. The antenna comprises a radiation structure and an excitation circuit. The radiation structure comprises a first metal layer and a second metal layer, with the first metal layer disposed at the first casing, the second metal layer disposed at the second casing, and a slot formed between the first metal layer and the second metal layer. The excitation circuit is disposed in the first casing, and comprising an electromagnetic wave emitting portion configured to emit an electromagnetic wave towards the slot.
