Abstract

This paper presents a compact filtenna for 5G communication applications, integrating a bandpass filter and a wideband antenna, both implemented on a 0.35 mm-thick Rogers RT/Duroid 5880 substrate. The bandpass filter features a rectangular layout with four symmetrically arranged slots and rounded inner edges, integrated with transmission lines at both input and output ends over a full ground plane. It achieves a 5.93 GHz bandwidth (21.42–27.35 GHz) with an S₁₁ of −31.03 dB at 24.1 GHz. The executed antenna consists of two circular radiating patches with embedded circular holes and a modified ground plane with a rectangular notch, providing a 23.3–27.2 GHz bandwidth and an S₁₁ of −41.66 dB at 25.58 GHz. The integrated filtenna exhibits dual resonances at 23.1 GHz and 25.02 GHz, with a 3.51 GHz operational bandwidth (22.5–26.01 GHz) and overall physical dimensions of 14.1 mm × 19 mm, corresponding to an electrical size of 1.08 λ₀ × 1.46 λ₀. The suitability of the recommended filtenna for 5G applications across several nations, including the US, Germany, France, Colombia, Italy, the UK, and Sweden, has been confirmed by measured findings that closely match simulation findings.

用于5G应用的紧凑型高性能印刷滤波器

本文介绍了一种用于5G通信应用的紧凑型滤波器，集成了带通滤波器和宽带天线，均在0.35 mm厚的Rogers RT/Duroid 5880基板上实现。带通滤波器采用矩形布局，具有四个对称排列的槽和圆形内缘，在整个地平面上与输入和输出端的传输线集成。实现5.93 GHz带宽（21.42 ~ 27.35 GHz）， 24.1 GHz时的S11为−31.03 dB。该天线由两个圆形辐射贴片和一个带矩形缺口的改进接地面组成，提供23.3-27.2 GHz的带宽和25.58 GHz时- 41.66 dB的S11。该集成滤波器具有23.1 GHz和25.02 GHz的双谐振，工作带宽为3.51 GHz (22.5-26.01 GHz)，整体物理尺寸为14.1 mm × 19 mm，对应的电尺寸为1.08 λ0 × 1.46 λ0。包括美国、德国、法国、哥伦比亚、意大利、英国和瑞典在内的几个国家的5G应用中推荐的滤波器的适用性已经得到了与模拟结果密切匹配的测量结果的证实。
