Claim 7:
8. A low-dielectric metal substrate, comprising a substrate layer and a metal layer disposed on the substrate layer, wherein the substrate layer is formed from a low-dielectric rubber resin material, the low-dielectric rubber resin material includes a low-dielectric rubber resin composition and inorganic fillers, and the low-dielectric rubber resin composition includes:
30 wt % to 40 wt % of a liquid rubber, wherein a molecular weight of the liquid rubber ranges from 800 g/mol to 6000 g/mol, and an iodine value of the liquid rubber ranges from 30 g/100 g to 60 g/100 g;
20 wt % to 40 wt % of a polyphenylene ether resin;
5 wt % to 10 wt % of a bismaleimide resin; and
20 wt % to 45 wt % of a crosslinker;
wherein the substrate layer has a dielectric constant measured at 10 GHz that is lower than or equal to 3.5.
