BROADBAND ANTENNA FOR MATCHING IMPEDANCE USING A TUBE-TYPE ELEMENT

摘要

PURPOSE: A broadband antenna for matching impedance using a tube type element is provided to implement various capacitances by variously forming a distance between matching members of an impedance matching/feeding unit. CONSTITUTION: A substrate(100) is made of dielectric materials with a preset dielectric constant. A radiation member(102) is electrically connected to an impedance matching/feeding unit(104). The impedance matching/feeding unit is connected to the substrate. A second matching member is electrically connected to a feeding point(106).
