In this article, a new 3-D printed dual tapered nested antenna design is presented. The antenna is composed of two tapered helical arms that wrap around each other in opposite orientations to exhibit orthogonal circular polarization schemes. The nested tapered helices are 3-D laser printed with copper platting. The outer helical arm is tailored to resonate at 2.4 GHz, while the inner arm is designed for operation at 5.4 GHz. The overall antenna structure is then arranged as an array of elements that can dynamically alter its lattice in either linear or triangular topologies in order to achieve reconfiguration in the radiation pattern. The change in topologies is driven by programmable robots that can reshape the antenna array’s radiation pattern dynamically and on demand. The whole system is measured and tested for various arrangements where the measured results show good agreement with the simulated data.

动态双锥形 3D 打印嵌套螺旋天线

在本文中，介绍了一种新的 3D 打印双锥形嵌套天线设计。天线由两个锥形螺旋臂组成，它们以相反的方向相互缠绕，以表现出正交圆极化方案。嵌套的锥形螺旋是 3D 激光打印的镀铜。外螺旋臂专为在 2.4 GHz 下共振而设计，而内臂设计为在 5.4 GHz 下工作。然后，整个天线结构被排列成一个元素阵列，这些元素可以以线性或三角形拓扑动态改变其晶格，以实现辐射方向图的重新配置。拓扑结构的变化是由可编程机器人驱动的，这些机器人可以动态地按需重塑天线阵列的辐射模式。
