Abstract

본 발명은 안테나가 휴대전화기 본체의 외부로 인출되었을 경우에는 1/4파장 와이어 안테나와 1/4파장 헬리컬 안테나가 결합되어 1/2파장 안테나로서 동작하며, 안테나가 내부로 삽입되었을 경우에는 1/4파장 헬리컬 안테나만 동작하되 내부로 삽입된 와이어 안테나가 내부에 장착되어 있는 단락 스위치와 결합하여 정합 회로를 구성함으로서 보다 안정되게 동작할 수 있도록 하는 신축 가능형 자기 임피던스 정합 이중 안테나를 제공하기 위하여, 전화기 본체(10)의 내, 외부로 자유롭게 이동할 수 있도록 연결된 1/4파장 와이어 안테나(20)와, 상기 1/4파장 와이어 안테나(20)에 전기적으로 결합시켜 전화기 본체(10) 외부로 돌출되도록 된 1/4파장 헬리컬 안테나(30)와, 안테나의 임피던스 정합을 위해 접지판(70) 소정의 위치에 장착된 단락스위치(60)를 포함하는 것을 특징으로 한다.In the present invention, when the antenna is drawn out of the main body of the cellular phone, the 1 / 4-wavelength wire antenna and the 1 / 4-wave helical antenna are combined to operate as the 1 / 2-wave antenna, and when the antenna is inserted into the antenna, 1 / In order to provide a flexible magnetic impedance matched dual antenna that operates only a four-wavelength helical antenna but operates more stably by forming a matching circuit in combination with an internally mounted short-circuit switch. The 1 / 4-wavelength wire antenna 20 connected to the inside and outside of the telephone body 10 so as to move freely and the 1 / 4-wavelength wire antenna 20 are electrically coupled to protrude out of the telephone body 10. 1/4 wavelength helical antenna 30 and a short switch 60 mounted at a predetermined position on the ground plate 70 for impedance matching of the antenna The features.
