CHIP ANTENNA FOR ADJUSTING RESONANCE FREQUENCY BY VIA HOLE

摘要

A chip antenna for adjusting resonance frequency by via hole is provided to variously form pathway of current by forming via hole between a main radiation body and sub radiation body, to control resonant frequency to lower band and to improve bandwidth. A chip antenna for adjusting resonance frequency by via hole comprises a main radiation body(10), a dielectric substrate(20), a sub radiation body(30), and one or more via holes(50). The main radiation body resonates in a fixed frequency band. The dielectric substrate is equipped to be parallel to the lower part of the main radiation body. The sub radiation body is formed in the lower surface of the dielectric substrate in the patterns of the predetermined shape.
