摘要

In this work, design and realization of high performance, low-cost X-band multilayeredcylindrical dielectric lens antenna (MLCDLA) is presented using 3D printing technology.Firstly, MLCDLA is designed and simulated in the complete 3D CST microwavestudio (MWS) within the X- band as consisting of six layers and being fed through aconventional rectangular waveguide (WR90). These layers are in the form ofcylindrical discs having different radii, thicknesses and made of a cheap polylacticacid material. These layers have also varying dielectric constant from 1.2 to2.7 that are compatible for fused deposition modeling (FDM) based 3D-printingprocess. Secondly, a prototype of MLCDLA is produced by using a FDM based3D-printer. 3D printed dielectric lens antenna is measured and a good return lossof almost more than 10 dB within the X-band with a high gain of 16-18 dBi areachieved as compared with the counterpart alternative designs. Thus, it can beconcluded that the proposed novel design and prototyping method not onlyachieves the high radiation performance characteristics along X-band but also is afast, low-cost, and effective method for prototyping dielectric lens structures forthe microwave applications.
