BROADBAND ANTENNA OF DUAL RESONANCE

摘要

Disclosed herein is a dual-resonance broadband antenna, and more particularly, to such a dual-resonance broadband antenna in which dual resonance is caused to occur using an antenna consisting of a strip line, a microstrip line or the like having a meander pattern so as to receive a signal for a wireless communication service at a relatively low frequency band, particularly, a signal with a terrestrial digital multimedia broadcasting (T-DMB) service frequency band of 174-216 MHz among a very high frequency (VHF) band. Particularly, the dual-resonance broadband antenna of the present invention is remarkably red uced in its size (length) as compared to a general helical antenna, a monopole antenna, a dipole antenna or the like while using a wireless communication service at a relatively low frequency band, thereby achieving miniaturization thereof. Further, it is possible to improve quality and reliability of the small-sized dual-resonance broadband antenna according to the present invention as well as enhance the qualities of a portable terminal and a transmission and reception device for wireless communication employing the antenna according to the present invention.
