INTERNAL INVERTED-F ANTENNA AND PORTABLE DEVICE HAVING THE SAME

摘要

PURPOSE: An internal inverted-F antenna and portable device with the same are provided to adjust a capacity component by adjusting the interval between radiation electrodes and easily match impedance and a resonant frequency. CONSTITUTION: An internal inverted-F antenna(100) includes a dielectric block(120), a first radiation electrode(140), and a second radiation electrode(160). A dielectric block is a polyhedron. The first radiation electrode is formed on one side of the dielectric block along with the outer circumference of the dielectric block. The second radiation electrode is separated from the first radiation electrode on the other side of the dielectric block. The first radiation electrode and the second radiation electrode are formed on the upper surface, both sides, and the bottom of the dielectric block. The first radiation electrode and the second radiation electrode have the same shape.
