摘　　要：This paper introduces an integrated design and manufacturing technology for L-band spiral antennas based on modified polyetheretherketone(PEEK).Initially,PEEK granules are blended with a laser activator for granulation and filamentation,and the antenna structure is fabricated using a fused deposition modeling(FDM)forming device.Subsequently,a pulsed infrared laser with a wavelength of 1064 nm is employed to etch spiral microstrips and feed network board circuit functional patterns on the surface of the formed PEEK material structure.Combined with electroless plating technology,metallization of the spiral lines on the PEEK surface and the feed network board circuitare achieved.Test results demonstrate that the integrated spiral antenna exhibits a standing wave ratio of 1.46 at a frequency of 1.575 GHz,with a gain of≥−2 dBi within a range of±70°,and a gain of≥−4 dBi within a range of±85°,essentially meeting the antenna specifications.The study indicates that this method holds research and application value for integrated products such as antennas and structural circuits.
