Abstract
An injection mouldable material and a method of making the material wherein the material comprises a mixture of an injection-mouldable polymer and a dielectric substance having a relatively high dielectric constant. The dielectric substance is preferably a ceramic. Such material is particularly suitable for the manufacture of planar antennas. The polymer preferably has a loss tangent equal to or less than 0.01 and greater than or equal to 0.002.
