Preferably, the material of described non-conducting material wire rod is macromolecular compound.
Preferably, the cross section of described conductor material is circular cross-section or oblong profile.
Compared with prior art, the beneficial effects of the utility model are as follows:
1, coil-type antenna of the present utility model by using one or one above enamelled wire as wire, and one or one above non-conducting material wire rod is arranged on outside wire, thus make this wire and non-conducting material wire rod turn to coil-type antenna by the mode of heating or solubilizer, by one week this non-conducting material wire rod of increase at this wire, make the gap enlargement between circuit, improve the radio-frequency performance of coil-type antenna.
2, coil-type antenna of the present utility model turns to coil antenna by wire and the spaced setting of non-conducting material wire rod, and in prior art close around coil mutual inductance larger, overall inductance is caused to exceed required value, simultaneously because in prior art wire close around, make the self-resonant frequency of its coil antenna very low, do not reach required value; By arranging the gap between this non-conducting material wire rod increase circuit between the wire of coil-type antenna, thus the overall inductance of coil-type antenna and self-resonant frequency can be made to reach desirable value.
