摘要

提出了一种采用表面PIN码(S-PIN)可重构频率和极化的固态等离子体缝隙天线。讨论了天线的设计结构。l型槽和4个s - pin采用SOI(Silicon-on-Insulator)半导体工艺嵌入，同轴底馈电微带线馈电。采用倒装芯片封装技术完成芯片与Pcb基板的互连，直流偏置电路通过金属孔引出。仿真结果表明，通过改变S-PIN开关状态，天线可以在水平极化和垂直极化之间切换，实现7.45GHz到16.5GHz的频率重构。由于S-PIN的插入损耗，天线的增益较低。辐射方向图表明，该天线在前向主波束方向上具有大于20dB的交叉极化比。

A Frequency and Polarization Reconfigurable Slot Antenna base on S-PIN using Flip-Chip Technology

In this paper, A solid-state plasma slot antenna with frequency and polarization reconfigurable by surface- PIN(S-PIN) is proposed. The design structure of the antenna is discussed. L-shaped slot and four S-PINs are embedded by SOI(Silicon-on-Insulator) semiconductor process and feed by coaxial bottom fed microstrip line. Flip chip packaging technology is used to complete the chip and Pcb substrate interconnection and the DC bias circuit is led out through metal holes. Simulation results show that by changing the state of S-PIN switch, the antenna can switch between horizontal polarization and vertical polarization, and can achieve frequency reconstruction from 7.45GHz to 16.5GHz respectively. The gain of the antenna is low due to the insertion loss of S-PIN. The radiation pattern shows proposed antenna has a cross polarization ratio of more than 20dB in the forward main beam direction.
