A fold-up multiplex antenna system is composed of a cellular phone housing(200), multiple coil antennas(310,410) and multiple bar antennas(320,420). A lst coil antenna(310) and a 2nd coil antenna(410) are connected together. And a coil antenna juncture(520) is conjoined with a circuit base material conjunction(510). As the coil antenna juncture(520) is connected with a circuit base material junction(510). The coil antenna and the circuit base material are connected. While a cellular phone is used, when an user pulls out the bar antennas(320,420) from a housing(200) and the bar antenna and the coil antennas(310,410) work together to increase gain.
