The design of the aperture-fed annular ring (AFAR) microstrip antenna is presented. This proposed design will ease the fabrication and usability of the 3D-printed and solderless 2D materials. This antenna consists of three layers: the patch, the slot within the ground plane as the power transfer medium, and the microstrip line as the feeding. The parameters of the proposed design are investigated using the finite element method FEM to achieve the 50 Ω impedance with the maximum front-to-back ratio of the radiation pattern. This study was performed based on four steps, each investigating one parameter at a time. These parameters were evaluated based on an initial design and prototype. The optimized design of 3D AFAR attained S around 17 dB with a front-to-back ratio of more than 30 dB and a gain of around 3.3 dBi. This design eases the process of using a manufacturing process that involves 3D-printed and 2D metallic materials for antenna applications.
本文介绍了孔径馈电环形微带天线（AFAR）的设计。这种设计方案将简化3D打印且无焊接的二维材料的制造过程和使用方式。该天线由三层组成：贴片、作为功率传输介质的接地平面内的缝隙以及作为馈电的微带线。使用有限元方法（FEM）对该设计方案的参数进行研究，以实现50Ω的阻抗以及辐射方向图的最大前后比。本研究基于四个步骤进行，每个步骤一次研究一个参数。这些参数是根据初始设计和原型进行评估的。3D AFAR的优化设计实现了约17dB的S值、超过30dB的前后比和约3.3dBi的增益。这种设计简化了将3D打印和二维金属材料用于天线应用的制造过程。
