摘要

提出了一种采用平面电磁带隙（EBG）设计的三频陷波超宽带（UWB）单极子天线。由阿基米德螺旋和数字间电容组成的EBG单元展示了陷波频率。在馈线附近具有EBG单元的天线仅占30×36mm2，具有三频带抑制特性。4.2GHz、5.2GHz和9.1GHz的三个陷波频带可用于C波段卫星下行链路、无线局域网（WLAN）和X波段无线电定位，用于海军雷达或军事应用。此外，所提出的设计是灵活的，可以通过改变EBG的尺寸来调谐不同的陷波带。将EBG单元电池放置在馈线附近后，对参数分析进行了详细研究，以显示耦合效应。还分析了输入阻抗和表面电流分布分析，以了解EBG在陷波频率下的影响。制作并表征了所提出的设计原型。在模拟结果和测量结果之间观察到相当大的一致性。

Planar EBG Loaded UWB Monopole Antenna with Triple Notch Characteristics

A triple band-notched ultra-wideband (UWB) monopole antenna using a planar electromagnetic bandgap (EBG) design is proposed. The EBG unit cell composed by an Archimedean spiral and inter-digital capacitance demonstrates the notch frequencies. The antenna with EBG cells near the feed line occupies only 30 × 36 mm2 with triple band-rejection characteristics. The three notched bands at 4.2 GHz, 5.2 GHz, and 9.1 GHz can be used in C-band satellite downlink, wireless local area network (WLAN), and X-band radio location for naval radar or military required applications. In addition, the proposed design is flexible to tune different notched bands by altering the EBG dimensions. The parametric analysis is studied in details after placing the EBG unit cells near the feed line to show the coupling effect. The input impedance and surface current distribution analysis are also analyzed to understand the effect of EBG at notch frequencies. The proposed design prototype is fabricated and characterized. A fairly considerable agreement is observed between simulated and measured results.
