Claim:
1. An antenna located on a substrate comprising: a radiating portion about λ/2 in length, wherein the λ indicates a wavelength of electromagnetic signals radiated by the antenna; a first coupling and feeding portion comprising a first feeding part and a first coupling part; and a second coupling and feeding portion comprising a second feeding part and a second coupling part; wherein the radiating portion comprises a first radiating part, a second radiating part and a third radiating part; the first radiating part, the third radiating part, and the second radiating part are connected in series and collectively form a meandering pattern; and the radiating portion is disconnected to a ground; wherein the substrate comprises a first surface and a second surface opposite to the first surface; the first coupling and feeding portion and the second coupling and feeding portion are located on the first surface; and the radiating portion is located on the second surface; the first coupling part comprises an elongated first coupling unit and an elongated second coupling unit, the first coupling unit and the second coupling unit perpendicularly connect together to form an “L” shape, a third radiating part projection on the first surface overlaps with the first coupling unit, a first gap is defined between the third radiating part and the first coupling unit due to a partition/separation of the substrate; and the second coupling part comprises an elongated third coupling unit and an elongated fourth coupling unit, the third coupling unit and the fourth coupling unit perpendicularly connect together to form another “L” shape, the third radiating part projection on the first surface overlaps with the third coupling unit, a second gap is defined between the third radiating part and the third coupling unit due to the partition/separation of the substrate.
