Abstract

This paper presents another technique of manufacturing the unit cells of spiral-shaped resonators - SR on the aluminium nitride (AlN) ceramics. In this technique the AlN plane surface is irradiated by the Nd:YAG (1.06 μm). As a result of the supplied energy, the rupture of aluminium and nitrogen bonds occurs. Consequently, on the dielectric surface the conductive aluminium "paths" are formed. Obtaining the low-ohm conductive structures allows deploying this method to manufacture SR structures which can be used in antennas in order to reduce their coupling. An advantage of the demonstrated method is a possibility of selective and direct metallization of the AlN ceramics surface without a mask as it is required in photolithography process, which greatly reduces the implementation time of the projected metamaterials structures.
