This paper presents a novel miniaturization approach by co-designing together a filter and an antenna. Indeed, contrary to a classical filter-antenna design, which presents a 50 Ω transition between the filter and the antenna, the co-design methodology proposed in this paper will prove that both the antenna and the filter can be optimized on a complex impedance. For this impedance, different from 50 Ω, the antenna volume can be reduced by more than 50% while presenting a high radiation efficiency. Moreover, the filter performance will be optimized on complex impedance loads without being affected compared to a classical 50 Ω filter. This new approach will be detailed and compared to a classical one in order to validate the improvement achieved by this co-design methodology. Prototypes have been manufactured and measurements confirm the benefits observed during the design phase.

通过协同设计实现滤波器天线装置的小型化



本文提出了一种新颖的小型化方法,将滤波器和天线共同设计。事实上,与经典的滤波器天线设计(滤波器和天线之间存在 50 Ω 过渡)相反,本文提出的协同设计方法将证明天线和滤波器都可以在复阻抗上进行优化。该阻抗与50Ω不同,天线体积可减小50%以上,同时呈现出较高的辐射效率。此外,与传统的 50 Ω 滤波器相比,滤波器性能将在复杂阻抗负载上得到优化,而不会受到影响。我们将详细介绍这种新方法,并将其与经典方法进行比较,以验证这种协同设计方法所取得的改进。原型已经制造出来,测量证实了设计阶段观察到的好处。
