Abstract

New microstrip ultra-wideband antenna is presented and measured in this paper. The antenna was calculated to operate in 3.1–10.6 GHz ultra-wideband frequency band, even though the measurements revealed that it covers the band 3.4–12 GHz. It's manufactured on the basis of Rogers RO4350B, which is appropriate for this band. Antenna's total size with SMA connector 72970 Pomona is 39 mm × 19 mm. The main goal stated in this paper is to prove the antenna's characteristics, simulated before, by carrying out full-time measurements in anechoic chamber. Particularly the return loss, VSWR, transfer function, input impedance and radiation pattern were measured and analyzed, which finally showed similarity of simulation and measured results. It can be announced that the antenna has very wide radiation pattern (more than 180°) and well-matched to 50 Ohm in the entire frequency band. Since it's small, compact, low profile it can be applied in many modern high-capacity communication systems, including UWB, hybrid optical fiber-wireless networks, 3G and future 5G networks.

微带超宽带天线测量

本文提出了一种新型微带超宽带天线，并对其进行了测试。根据计算，该天线工作在3.1-10.6 GHz的超宽带频段，尽管测量显示它覆盖了3.4-12 GHz的频段。它是在罗杰斯ro450b的基础上制造的，适用于这个波段。采用SMA连接器72970 Pomona的天线总尺寸为39mm × 19mm。本文的主要目标是通过在暗室中进行全时测量来验证之前模拟的天线特性。对回波损耗、驻波比、传递函数、输入阻抗和辐射方向图进行了测量和分析，仿真结果与实测结果基本一致。可以宣布，该天线具有非常宽的辐射方向图(超过180°)，并且在整个频段内与50欧姆匹配良好。由于它小巧、紧凑、低调，可以应用于许多现代高容量通信系统，包括超宽带、光纤-无线混合网络、3G和未来的5G网络。
