METHOD FOR SETTLING THE BROADBAND SPECIFICITY OF A BROADBAND STUBBY ANTENNA AND A BROADBAND STUBBY ANTENNA USING THE SAME

摘要

PURPOSE: A broadband stubby antenna is provided to be capable of improving a broadband characteristic of an antenna and of easily adjusting a resonance frequency and the broadband characteristic. CONSTITUTION: A part of a PCB is used as a PCB dielectric(11). The first and second ground metal conductors(12,13) are formed at top and bottom sides of the PCB dielectric and form a ground surface. A coupling dielectric(20) is extended from one side of the PCB dielectric. A metal conductor for coupling adjustment(30) is formed at a lower side of the coupling dielectric so as to be extended from the second ground metal conductor. The first power supply metal conductor(40) is formed at a top side of the coupling dielectric so as to be spaced apart from the first ground metal conductor and to be overlapped partially with the metal conductor for coupling adjustment. A metal conductor(50) of a meander type has one side connected to the first power supply metal conductor. A meander line(52) is formed at the other side of the metal conductor. A dielectric for protection surrounds the meander line.
