This work discusses the design of a microstrip patch antenna and its use as an orientation-agnostic radiator in an origami-inspired folding antenna array. The antenna is based on a perturbed circular patch design that is impedance matched to reside in a radial feed network for a 2 × 2 array. This 2 × 2 array can be switched to provide sum and difference pattern behaviour. Both the feed network and the ground plane are modified to enable folding of the structure according to the Miura-ori pattern. The performance of a circularly polarised array is evaluated for a comprehensive range of fold angles to evaluate the impact of physical reconfiguration. Results for a simulated and fabricated circularly polarised array are provided for a 3 GHz design.

圆极化折纸启发的折叠贴片天线子阵列

这项工作讨论了微带贴片天线的设计及其在折纸风格的折叠天线阵列中作为与方向无关的辐射器的用途。该天线基于扰动的圆形贴片设计，其阻抗匹配以驻留在用于2×2阵列的径向馈电网络中。可以切换此2×2阵列以提供求和和差模式行为。修改了馈电网络和接地平面，以根据Miura-ori模式折叠结构。针对折叠角的全面范围评估了圆偏振阵列的性能，以评估物理重构的影响。为3 GHz设计提供了模拟和制造的圆偏振阵列的结果。
