Multi-Band Antenna

摘要

A multi-band antenna includes a base portion, a high-frequency radiating portion, a feeding portion and a low-frequency radiating portion. The base portion has a first transverse edge and a second transverse edge parallel to and opposite to the first transverse edge. The high-frequency radiating portion includes an inductance portion, a first extending portion, a second extending portion and a third extending portion. One side of a bottom of the feeding portion defines a feeding point. The low-frequency radiating portion has a bending portion, a coupling portion and an auxiliary portion. The base portion, the high-frequency radiating portion, the coupling portion and the auxiliary portion are coplanar. The base portion, the high-frequency radiating portion, the coupling portion and the auxiliary portion together with the bending portion are located in two perpendicular planes.

1. A multi-band antenna, comprising:
a base portion having a first transverse edge and a second transverse edge parallel to and opposite to the first transverse edge, the first transverse edge being in front of the second transverse edge; a high-frequency radiating portion including an inductance portion extending forward from a left side of the first transverse edge of the base portion, a first extending portion extending forward from a right side of the first transverse edge of the base portion, a second extending portion extending leftward from a front end of the first extending portion and a third extending portion extending forward from a left side of a front edge of the second extending portion; a feeding portion extending downward and then extending forward from the second transverse edge of the base portion, one side of a bottom of the feeding portion defining a feeding point; and a low-frequency radiating portion having a bending portion extending forward, then extending downward and further continuously meandering leftward, a coupling portion extending rearward and then extending towards the second extending portion from a distal end of the bending portion, and an auxiliary portion extending rearward and then extending towards the inductance portion from a distal end of the coupling portion, the base portion, the high-frequency radiating portion, the coupling portion and the auxiliary portion being coplanar, the base portion, the high-frequency radiating portion, the coupling portion and the auxiliary portion together with the bending portion being located in two perpendicular planes.
