1. a mobile phone, comprises a pcb board and the antenna being connected with pcb board, it is characterized in that, described inAntenna comprises medium substrate, is attached to the first sheet metal and second sheet metal on relative two surfaces of medium substrate,Be provided with the first feeder line, the second feeder line around the first sheet metal, around the second sheet metal be provided with the 3rd feeder line,The 4th feeder line, described the first feeder line and the second feeder line are all by the first sheet metal described in coupled modes feed-in, instituteState the 3rd feeder line and the 4th feeder line all by the second sheet metal described in coupled modes feed-in, described the first sheet metalUpper hollow out has asymmetrical the first micro groove structure and the second micro groove structure to form the first gold medal on the first sheet metalBelong to cabling, on described the second sheet metal hollow out have asymmetrical the 3rd micro groove structure and the 4th micro groove structure withOn the second sheet metal, form the second metal routing, described the first feeder line is electrically connected with the 3rd feeder line, and described secondFeeder line is electrically connected with the 4th feeder line, and described antenna is preset with the space that electronic component embeds, described electronics unitPart is perceptual electronic component, capacitive electronic component or resistance, and the model of described perceptual electronic component inductance valueBe trapped among between 0-5uH, the scope of described capacitive electronic component capacitance is between 0-2pF, and described space isBe formed on the pad on described antenna;

  • Wherein, described the first sheet metal is not connected or connects with the second sheet metal;

    When in described the first sheet metal and the unconnected situation of the second sheet metal, described the first sheet metal and secondBetween sheet metal by capacitively coupled mode feed;

    Realize first by the thickness that changes described medium substrateThe resonance of sheet metal and the second sheet metal;

    When in the situation that described the first sheet metal is connected with the second sheet metal, described the first sheet metal and the second gold medalBelong between sheet by inductive coupled mode feed;

    Wherein, described spatial placement between the first feeder line, the second feeder line, the first feeder line and the first sheet metal,In at least one of between the second feeder line and the first sheet metal and these five positions of the first sheet metal, or described inSpatial placement between the 3rd feeder line, the 4th feeder line, the 3rd feeder line and the second sheet metal, the 4th feeder line andIn at least one of between two sheet metals and these five positions of the second sheet metal.
