| 摘 要： | 针对超宽带通信系统中脉冲信号传输保真度的问题, 分析了保真度与脉冲天线的相频特性、增益-频率特性的关系, 提出通过调整天线的增益特性来对信号在自由空间产生的传输损耗进行平衡补偿的技术.通过对一款高保真印刷半锥形单极天线(Half-Printed Tapered Monopole Antenna, Half-PTMA)增益-频率特性的仿真分析, 以及将此补偿技术应用到一款超宽带平面单极天线的设计改进, 改进后保真度提高了5%, 验证了文中补偿技术的有效性, 为超宽带脉冲天线的高保真设计提供了有价值的设计依据.

| Abstract: | The relationship between fidelity of pulse signals and phase-frequency and gain-frequency characteristics of ultra-wideband antennas is studied,and a technique to compensate for the transmission loss in free space via the design of antenna gain is proposed.The simulation of a high-fidelity ultra-wideband printed tapered monopole antenna(PTMA) gain and the compensation technology in the application of an ultra-wideband planar monopoly antenna fidelity with 5％ improvement has verified the compensation technique,which is valuable to the design of high-fidelity ultra-wideband pulse antennas. |

| Keywords: | ultra-wideband antenna pulse fidelity gain transmission loss |
