摘要

提出了一种基于超表面结构的超宽带(UWB)低轮廓天线。该天线由两层基板、宽槽(WS)和微带馈线组成。超表面结构的引入使天线在更高频率处产生新的谐振点。同时，微带馈线的开槽使阻抗匹配更好。仿真结果表明，该天线阻抗带宽达到了98.47% (3.31 ghz ~ 9.73 ghz)。其尺寸为54mm×54mm × 3.7mm，整个频段的最大增益为7.3dBi，−3dB增益带宽为4.79GHz ~ 9.7GHz。

An Ultra-Wideband Microstrip Slot Antenna based on Metasurface

In this paper, an ultra-wideband (UWB) low-profile antenna based on metasurface structure is proposed. The antenna consists of two layers of substrates, a wide slot (WS) and a microstrip feedline. The introduction of the metasurface structure generates a new resonance point of the antenna at higher frequencies. At the same time, slotting the microstrip feedline makes the impedance match better. Simulation results indicate that the proposed antenna attains a 98.47% impedance bandwidth (3.31GHz-9.73GHz). With a size of 54mm×54mm × 3.7mm the maximum gain of the whole band is 7.3dBi and the −3dB gain bandwidth is from 4.79GHz to 9.7GHz.
