| 摘要 |
The present invention relates to a folded monopole antenna which includes an antenna pattern in which an impedance is decreased to a metal itself resistance based on a feeding point which is provided in an upper portion of a wireless instrument and is continuously extended in a linear shape having a certain thickness and is formed in an upward direction for thereby forming a value L, and an offset point which is provided near the feeding point for thereby forming a value C, and an antenna casing which protects and insulates the antenna pattern. In the present invention, it is possible to obtain a lower gain compared to a conventional helical antenna, and a value Q is largely enhanced. |
