This study proposes an innovative patch antenna design for multi-band operation and high radiation efficiency. The design target is the structural shape of a patch and a ground plane. The operating range of patch antenna is set to both the 5G band (3.4−3.7 GHz) and the Bluetooth range (2.4−2.48 GHz). The design process follows two steps, the genetic algorithm (GA) and the binary method. Although the GA has been widely used for patch antenna design, however, it is hard to improve the performance only using the GA due to its restriction on design constraints. Therefore, this study proposes the successive application of the binary method after the GA to derive a unique topological shape of a patch antenna. The application of the binary method enables the design constraint for bandwidth enhancement. Design results are verified through experimental measurements using fabricated antennas.

使用 gA 和二进制方法进行双频应用的贴片天线设计

本研究提出了一种用于多频段操作和高辐射效率的创新贴片天线设计。设计目标是贴片和地平面的结构形状。贴片天线的工作范围设置为 5G 频段 (3.4-3.7 GHz) 和蓝牙范围 (2.4-2.48 GHz)。设计过程遵循两个步骤,遗传算法 (GA) 和二进制方法。尽管遗传算法已广泛用于贴片天线设计,但由于其设计约束,仅使用遗传算法很难提高性能。因此,本研究建议在 GA 之后连续应用二进制方法来推导出贴片天线的独特拓扑形状。二进制方法的应用使带宽增强的设计约束成为可能。
