摘要

本文提出了一种超宽带CPW馈电的紧凑型单极贴片天线的设计方案。该天线的尺寸为22×18×1.6 mm，在超宽带频率范围4.86–13.66 GHz（模拟）和4.93–13.54 GHz（测量）上运行良好，覆盖C、X和部分Ku波段应用。所提出的设计包括一个有缺陷的接地平面和U形辐射贴片以及两个方形寄生贴片，以实现超宽带（UWB）操作。通过测量结果验证了性能矩阵，测量结果表明宽阻抗带宽（93.2%），最大增益为4dBi，最大辐射效率接近95%；此外，3D增益模式表现出所提出的设计的近似全向模式。原型已通过ANSYS使用HFSS（高频结构模拟器-18）进行建模，并使用矢量网络分析仪E5071C进行制造和测试。

Design of a Compact CPW-Fed Monopole Antenna With Asymmetrical Hexagonal Slot Loaded Ground Structure for C/X/Ku Band Applications

Abstract A novel design of ultra-wideband CPW-fed compact monopole patch antenna is presented in the article. The size of the antenna is 22 × 18 × 1.6 mm and it operates well over an ultra-wideband frequency range 4.86–13.66 GHz (simulated) and 4.93–13.54 GHz (measured) covering C, X and partial Ku band applications. The proposed design consists of a defected ground plane and U-shape radiating patch along with two square shape parasitic patches in order to achieve the ultra-wideband (UWB) operations. The performance matrix is validated through measured results that indicate the wide impedance bandwidth (93.2 %) with maximum gain of 4 dBi with nearly 95 % of maximum radiation efficiency; moreover, the 3D gain pattern manifests approximately omni-directional pattern of the proposed design. The prototype has been modelled using HFSS (High Frequency Structure Simulator-18) by ANSYS, fabricated and tested using vector network analyser E5071C.
