| 摘 要： | 对所设计的以硅为基底,中心频率在1.9GHz的圆极化微带天线进行了介绍.由于硅的介电常数较高,导致天线效率很低,在高频率段容易产生表面波,所以采用挖空气腔来降低相对介电常数.设计出的微带天线尺寸为55 mm×55 mm,尺寸较大,因而采用了加载和曲流技术来减小天线的尺寸.在此基础上设计出2×2天线阵列,并用HFSS进行仿真,方向图和增益均达到要求.

| Abstract: | In this paper,the authors design MEMS Silicon-based patch array antenna element whose center frequency is 1.92 GHz.Because high dielectric constant of silicon degrades an antenna efficiency and excites surface waves especially at high frequency,so the authors give birth to an air cavity to reduce the equivalent permittivity.Because the antenna is large,so we use the technology of loading and mendering to reduce the size.Furthermore,2×2 dissymmetrical microstrip array antenna is designed with the element and simulated in HFSS.The antenna pattern and gain are both content. |
