ANTENNA STRUCTURE HAVING A RESONANT FREQUENCY AND A RADIATION PROPERTY CAPABLE OF BEING VARIED FOR CONTROLLING THE RADIATION PROPERTY

摘要

PURPOSE: An antenna structure having a resonant frequency and a radiation property is provided to vary the resonant frequency without the physical variation of length by adjusting an angle between first and second antenna members.;CONSTITUTION: A first antenna member(220) is formed at one side of a first supporting member(210). A second supporting member is inserted into the inner space of the first supporting member. A second antenna member(320) is formed at one side of the second supporting member. A third antenna member(400) is separated from the first and second antenna members. The third antenna member is formed at the circumference of the first and second antenna members.;COPYRIGHT KIPO 2013
