ABSTRACT:
The present invention discloses a low-cost coaxial cable fed inverted-L antenna with a structure using only one coaxial cable and extending an internal conductor outside one end of the coaxial cable to a predetermined length outside an external conductor on the other end, and then bending the coaxial cable backward in an opposite direction along the external conductor and parallel to the direction of the external conductor to extend to a predetermined length outside to define a radiating member, which doesn't require additional components or any other manufacturing procedure, and will greatly lower the production and manufacturing costs of the antenna and improve the yield rate of production.
