Patent ID: 8299969

Claim:
A multiband antenna, comprising: a radio unit including a first radio member and a second radio member connected to the first radio member, the first radio member and the second radio member having similar shapes and sizes to each other and aligned with each other; and a base circuit board connected to the second radio member to provide feed signals to the radio unit and connect the radio unit to the ground; wherein the first radio member independently sends/receives wireless signals at a first frequency, and the second radio member is coupled with the first radio member, thereby cooperating with the first radio member to send/receive wireless signals at a second working frequency; wherein the first radio member and the second radio member are both planar sheets positioned parallel to the base circuit board; wherein the first radio member define a first slot therein, a first arm portion and a second arm portion are correspondingly formed at two sides of the first slot, an end of the first arm portion is connected to an end of the second arm portion, and another end of the first arm portion and another end of the second arm portion are separated from each other by the first slot; wherein the second radio member define a second slot therein, a third arm portion and a fourth arm portion are correspondingly formed at two sides of the second slot, an end of the third arm portion is connected to an end of the fourth arm portion, and another end of the third arm portion and another end of the fourth arm portion are separated from each other by the second slot; and wherein the radio unit further includes a connecting member, and the connecting member is a planar sheet perpendicularly connected between the end of the second arm portion separated from the first arm portion and the end of the fourth arm portion separated from the third arm portion.
