METAL CLAD LAMINATED SHEET

摘要

PURPOSE:To process a metal clad laminated sheet into a compact antenna by planning common to a case processing a PPO resin laminated sheet or a BT resin laminated sheet into an antenna. CONSTITUTION:A laminated sheet l is formed by impregnating a base material composed of glass fiber cloth with fluoroplastic and curing the impregnated cloth and a metal foil 2 is.laminated to the laminated sheet 1. The dielectric constant of the laminated sheet is set to 3.1-4.5. By setting the dielectric constant of the laminated sheet l to 3.1 or more, the laminated sheet can be processed into a small-sized antenna and the dielectric constant thereof can be made approximate to that of a PPO or BT resin laminated sheet.
