“…Varying the constant from 12 to 90 of a given material was successfully realized in [6], [7] without losing the desirable low-loss characteristics. Through 3D printing, the same result can easily be achieved [8], [9]. A latticetype structure can be designed to allow for the desired infill percentage, and through this, a specified dielectric constant can be obtained.…”

This paper investigates the use of 3D-printed alumina ceramics to achieve variable dielectric constants for novel microwave applications. An introduction to lithography-based ceramic manufacturing exhibits the novel process and material properties, while detailing printing techniques for achieving gradient and equivalent dielectric constants. Printed samples of non-homogeneous dielectrics are presented and briefly discussed. Potential end-use for microwave components are discussed with emphasis on future filter applications.

In this paper the authors present the development process of a novel 3D printed 4-pole dielectric filled waveguide filter which was implemented with embedded lattice elements. The final part is sealed to simplify the metallisation process. The authors provide useful fabrication techniques and tuning methods to improve the manufactured part and make the design less sensitive to fabrication tolerances.

A Dielectric Resonator Antenna operating in circular polarization is presented. The proposed antenna is formed by a uniaxial anisotropic dielectric and a ground plane. The optimization of the permittivity tensor and antenna dimensions is performed both theoretically and numerically using an Eigen mode analysis in Ansys HFSS. A good agreement is obtained for the resonant frequencies and quality factors of the different modes. The uniaxial anisotropic DRA radiates two degenerate orthogonal modes, TE111 x and TE111 y , with equal amplitudes and 90° phase difference in order to achieve circular polarization. An impedance bandwidth of 9.8% is accomplished and a broadside radiation pattern with left-hand circular polarization (LHCP) is achieved in simulation. Furthermore, an Axial Ratio (AR) of 0.06 dB at 2.45 GHz and a 3-dB AR bandwidth of 2.04% are obtained. The maximum simulated directivity is equal to 6.56 dBi.
