Abstract

This article presents a compact ultra-wideband (UWB) circular monopole antenna with a frequency-selective surface (FSS) for gain enhancement. The proposed antenna has a circular patch with circular cuts at the edges and is excited by a microstrip feed. The bottom plane is truncated and further modified by two triangular cuts at the sides and one rectangular cut in the middle to improve the radiation characteristics of the UWB antenna. The antenna is designed on an FR-4 substrate with a thickness of 1.6 mm, a relative permittivity of 4.3, and planner dimensions of 30 mm × 30 mm. To improve the proposed antenna’s gain, an FSS is designed that consists of periodic unit cells of metal printed on the upper layer of an FR-4 substrate with dimensions of 0.11λ × 0.11λ at the lowest operating frequency of 3.3 GHz. The FSS shows a very low transmission coefficient and linearly reducing reflection phase with increasing frequency over a frequency range of 3.3–10.8 GHz. The gain of the proposed antenna is increased from 3 dB to 8.1 dB at 9 GHz by placing the antenna on the FSS. Moreover, the prototype of the proposed antenna is fabricated, and the experimental results are measured, which show close agreements with simulated results. The FSS-based antenna has directional radiation patterns, making it a potential candidate for ground-penetrating radar and UWB applications.
用于增益增强应用的新型紧凑型超宽带选频表面天线
本文提出了一种紧凑的超宽带(UWB)圆形单极天线,该天线具有频率选择表面(FSS)以增强增益。所提出的天线有一个圆形的贴片,边缘有圆形的切口,并由微带馈电激发。底部平面被截断,并通过两侧的两个三角形切口和中间的一个矩形切口进一步修改,以改善UWB天线的辐射特性。天线设计在厚度为1.6 mm、相对介电常数为4.3、规划尺寸为30 mm × 30 mm的FR-4衬底上。为了提高天线的增益,设计了一种FSS,该FSS由印刷在FR-4衬底上层的金属周期单元组成,尺寸为0.11λ × 0.11λ,最低工作频率为3.3 GHz。在3.3 ~ 10.8 GHz频率范围内,FSS具有很低的传输系数和随频率增加而线性减小的反射相位。通过将天线置于FSS上,所提出的天线在9ghz时的增益从3db增加到8.1 dB。制作了天线样机,并对实验结果进行了测量,结果与仿真结果吻合较好。基于fss的天线具有定向辐射方向图,使其成为探地雷达和超宽带应用的潜在候选者。
