    摘要: An antenna and method of manufacture are described in which a spiral microwave antenna is formed over a domed substrate of epoxy glass resin. A copper foil member is formed over a die by spinning or burnishing to a domed configuration matching that of the substrate. The copper member is then given a coating of primer and clamped over the substrate which has been coated with an epoxy cement, and the assembly subjected to heat and pressure sufficient to bond the foil to the substrate. The assembled antenna blank is then coated with photo-resist material and illuminated from a source of collimated light through a photo negative which is carefully centered to expose the desired spiral pattern on the photo-resist material. The photo-resist is then developed and rinsed, and the blank is baked to harden the exposed photo-resist. The blank is then etched to remove the unwanted copper, leaving the desired antenna pattern. The copper pattern is then preferably plated with tin and the assembly trimmed and drilled as desired.
