Abstract:
1. A portable terminal, comprising: a terminal body; a circuit board integrated with the terminal body, the circuit board having at least a front surface, a back surface, a first lateral surface, and a second lateral surface, wherein the first lateral surface and the second lateral surface are formed substantially vertically with respect to the front surface and the back surface; a first antenna provided on the front or back surface of the circuit board proximate to an end portion of the terminal body, a first ground being formed on the front surface and used by the first antenna; an antenna assembly integrated with the terminal body, the antenna assembly comprising at least one diversity antenna; a second ground arranged on the first lateral surface of the circuit board such that a first portion of the second ground is in contact with the first lateral surface and a second portion of the second ground, which extends from the first portion of the second ground, is not in contact with the first lateral surface; and a third ground arranged on the second lateral surface of the circuit board such that a first portion of the third ground is in contact with the second lateral surface and a second portion of the third ground, which extends from the first portion of the third ground, is not in contact with the second lateral surface, the second portion of the second ground facing the second portion of the third ground, wherein the second ground and the third ground, which are independent from the first ground, are formed substantially vertically with respect to the first ground, wherein the at least one diversity antenna comprises:
