Patent ID: 8471778

Claim:
A solid dual-band antenna device, comprising: an antenna structure, comprising: a ground portion having a first side and a second side opposite to the first side; an extending ground portion non-coplanarly extended from the first side, wherein a first included angle is formed by an intersection of the ground portion and the extending ground portion; a first radiating portion having a first length, a first end, a second end, a third side adjacent to the second side, a fourth side opposite to the third side, and a seventh side disposed along a specific line, wherein a second included angle is formed by an intersection of the second side and the third side; a second radiating portion having a second length, a third end, a fourth end, a fifth side adjacent to the fourth side, and a sixth side opposite to the fifth side, wherein the sixth side is disposed along the specific line, and a third included angle is formed by an intersection of the fourth side and the fifth side so that the ground portion, the first radiating portion and the second radiating portion present an S-shape or a Z-shape on a first plane; a first slot disposed at an arbitrary position of the second radiating portion; an extending radiating portion having an eighth side opposite to the sixth side and the seventh side and non-coplanarly extended from the sixth side and the seventh side, wherein a fourth included angle is formed by an intersection of the second radiating portion and the extending radiating portion, wherein the extending radiating portion has a second slot extended from the eighth side to one of the sixth side and the seventh side; and a feeding portion disposed at an junction of the second end and the third end, wherein the first length is different from the second length.
