    Abstract: In a state that a whip antenna 101 is contained in a housing 110 of a cellular phone, a minute space d1 is formed between a feeding spring 117 and an attaching member 112 conductive to a screw antenna base portion 120, so as to generate electrostatic capacitance, which is equivalent to the impedance characteristic of mono-pole antenna 114. Then, electrostatic capacitance and a coil portion of a screw antenna 113 constitute an LC series resonance circuit so as to improve the wide band of screw antenna 113.
