The antenna comprises an FPC mainboard and a pressure-sensitive adhesive layer arranged on the lower surface of the FPC mainboard, wherein the pressure-sensitive adhesive layer is prepared by the following method: mixing 20-30 parts by weight of acrylic prepolymer, 30-40 parts by weight of vulcanized nano styrene-butadiene rubber, 50-70 parts by weight of reactive diluent monomer and 1-3 parts by weight of photoinitiator, coating the mixture on the upper surface of a release film to a coating thickness of 10-30 mu m, carrying out UV curing to obtain a pressure-sensitive adhesive layer, and attaching the upper surface of the pressure-sensitive adhesive layer to the lower surface of an FPC (flexible printed circuit) main board to obtain the antenna.
There are three major requirements for pressure sensitive adhesive for FPC antennas: firstly, the FPC antenna needs to have higher bonding strength, so that the FPC antenna needs to be bonded after being bent under certain conditions, the pressure-sensitive adhesive can be subjected to larger rebound force, and the pressure-sensitive adhesive needs to have high bonding strength to prevent the pressure-sensitive adhesive from dislocating; secondly, the pressure-sensitive adhesive needs to have better toughness and higher elongation at break resistance due to the requirement of bending; third, a lower thickness is required, which is a development demand for electronic products to be light and thin. According to the invention, the vulcanized nano styrene-butadiene rubber is added into the pressure-sensitive adhesive component, and the unsaturated bond and the vulcanized grafted group of the vulcanized nano styrene-butadiene rubber can be crosslinked with the acrylic monomer, so that as an additional crosslinking prepolymer, the crosslinking can be developed from a body structure to a linear structure, and the toughness of the pressure-sensitive adhesive can be improved; in addition, the vulcanized nano styrene-butadiene rubber is used as an elastomer, so that the reinforcing and toughening effects can be improved, the nano styrene-butadiene rubber can be used as a pure rubber layer, a PET carrier layer is not required to be involved, and the thickness is favorably reduced; in addition, the proper amount of the vulcanized nano styrene butadiene rubber can obviously improve the adhesive property of the pressure-sensitive adhesive, so that the pressure-sensitive adhesive has higher peel strength.

the nanometer vulcanized butadiene-styrene rubber is replaced by VP-401 (vulcanized nanometer butadiene-acrylonitrile rubber) in equal weight parts.
