ABSTRACT:
A small size thin type antenna using a thin type structure having a wavelength compaction effect without using a bulk conductive material and a high frequency module using the same are disclosed. The small size thin type antenna comprises an open stub3including at least one transmission line13, 16, a connecting line5including at least one transmission line15,and a short stub4including a transmission line14.A characteristic impedance Zo of the open stub3is determined to be lower than a characteristic impedance Zb of the connecting line5and a characteristic impedance Zs of the short stub4.
