Additively Manufactured Alumina Substrates with Tailored Permittivity for mm-Wave Antennas
A method for additive manufacturing of ceramic substrates with desired dimensions is proposed in which permittivity is tailored by varying the sintering temperature. Samples are used as dielectric substrates for a mm-wave bow-tie antenna. A wide tuning range, from 83 GHz to 93 GHz, in the operating frequency of the antenna can be achieved by simultaneously adjusting the substrate thickness and the permittivity, without changing the antenna structure itself.
