Abstract

The versatility and utility of metallic corrugated leaky wave antennas have been time and again proved along several works. However, the weight of a purely metal structure can be a drawback for certain applications, such as satellite communications or similar purposes, where the employment of light devices is an essential requirement. In this work, it is demonstrated the feasibility of a 3D-printed structure which offers radiation features comparable to those presented by classical metallic antennas. Measurements and simulations show an overall good agreement, displaying a gain of 17 dB with a 3.5º beamwidth and -10 dB side lobe level at 96 GHz for an elliptical Bull’s Eye antenna with a tilted beam
pointing at 16.5º. Experimental and numerical results are substantiated by the theoretical analysis of optimum off-axis beaming and a step-by-step design and manufacturing procedure.
