Summary:PURPOSE: To provide a compact broadband plane multiplex antenna operable in at least two frequency bands, and to provide a portable terminal. CONSTITUTION: The plane multiplex antenna comprises: a tabular radiation conductor 3 having a slit 2 composed of a U-shaped slit 2a and an open slit 2b opening a part of the slit 2a and at least two resonance frequencies; and feeder lines 4a, 4b for feeding the radiation conductor 3. The U-shaped slit 2a and the open slit 2b have widths determined according to the band, this allowing the first and the second resonance frequencies to be set over a broad band, and enabling the miniaturization. 본 발명에 따르면 크기가 작고 대역이 넓고 적어도 2개의 주파수 대역에서 작동하는 것이 가능한 평판 다중 안테나와 그것을 사용하는 휴대용 단말기가 제공된다. 평판 다중 안테나는 적어도 2개의 동조 주파수를 갖고, U형 슬릿 및 U형 슬릿의 한쪽 단부를 개방한 개방 슬릿을 구비한 방열 도체와 방열 도체에 전원을 공급하는 급전선을 포함한다.
