Low-cost coaxial cable fed inverted-L antenna
First Claim
1. A low-cost coaxial cable fed inverted-L antenna having a coaxial cable, and said coaxial cable comprising:
- an internal conductor, being a core axis of the coaxial cable and acting as a wireless signal transmission line;
an external conductor, acting as a mask and a ground line;
an insulating dielectric material, disposed between said internal and external conductors and separating said internal and external conductors by a predetermined distance, thereby a concentric conductor being defined between said internal and external conductors;
an insulating external skin, being wrapped around the exterior of said external conductor;
wherein one end of said coaxial cable connecting to a control circuit of a wireless communication device;
one end of said internal conductor being extended to a predetermined distance outside the external conductor and then bent backward in an opposite direction and along said external conductor and parallel to the direction of said external conductor, and then extended to define a radiating member with a predetermined length.

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.
