摘要

A multi-band antenna includes a grounding portion, a main radiating portion, and a shielding wall. The main radiating portion includes a first radiating portion having a first feed end and a second radiating portion having a second feed end. The first and second radiating portions are structurally symmetrical. The main radiating portion and the shielding wall are arranged on opposite sides of the grounding portion.

主权项

1. An antenna, comprising:
a grounding portion having a first edge portion and a second edge portion; a main radiating portion arranged on the first edge portion of the grounding portion, the main radiating portion having a first radiating portion and a second radiating portion formed substantially symmetrically, the first radiating portion having a first feed end, the second radiating portion having a second feed end; and a shielding wall arranged on the second edge portion of the grounding portion across from the main radiating portion; wherein a T-shaped structure is formed in the middle of the main radiating portion, wherein the first feed end and the second feed end are formed in opposite directions at respective sides of the T-shaped structure; wherein a first signal transmission cable is connected to the first feed end for feeding a first antenna signal, and a second signal transmission cable is connected to the second feed end for feeding a second antenna signal; wherein the first radiating portion has a first arm and a second arm, and the first arm and the second arm are arranged adjacently, wherein the second radiating portion has a third arm and a fourth arm, and the third arm and the fourth arm are arranged adjacently, wherein the second arm and the fourth arm extend sideways from a central portion of the main radiating portion to form the T-shaped structure, wherein the first arm and the third arm extend from the side portions of the main radiating portion toward the central portion thereof in forming a pair of opposing inverted L-shaped structures, the T-shaped structure being surrounded by the inverted L-shaped structures.
