Abstract

In this article, an inkjet-printed circular-shaped monopole ultra-wideband (UWB) antenna with an inside-cut feed structure was implemented on a flexible polyethylene terephthalate (PET) substrate. The coplanar waveguide (CPW)-fed antenna was designed using ANSYS high-frequency structural simulator (HFSS), which operates at 3.04-10.70 GHz and 15.18-18 GHz (upper Ku band) with a return loss < -10 dB and a VSWR < 2. The antenna, with the dimensions of 47 mm × 25 mm × 0.135 mm, exhibited omnidirectional radiation characteristics over the entire impedance bandwidth, with an average peak gain of 3.94 dBi. The simulated antenna structure was in good agreement with the experiment's measured results under flat and bending conditions, making it conducive for flexible and wearable Internet of things (IoT) applications.

摘要

在本文中，一种具有内切馈电结构的喷墨打印圆形单极超宽带（UWB）天线被制作在柔性聚对苯二甲酸乙二酯（PET）基板上。采用ANSYS高频结构模拟器（HFSS）设计了共面波导（CPW）馈电天线，该天线工作在3.04 - 10.70 GHz和15.18 - 18 GHz（上Ku波段），回波损耗 < -10 dB，电压驻波比 < 2。该天线尺寸为47 mm×25 mm×0.135 mm，在整个阻抗带宽内呈现全向辐射特性，平均峰值增益为3.94 dBi。模拟的天线结构与在平坦和弯曲条件下实验测量结果吻合良好，有利于柔性和可穿戴物联网（IoT）应用。
