In this paper the dimension parameters which influence the electrical properties of the biconical antenna is discussed by means of simulation and experimental test. And a biconical omni-directional antenna array operating within 0.8~3GHz is designed. Its design parameters and the results of the simulation including curves of the VSWR, radiation pattern and the gain within the band are also given.

本文通过仿真与实验测试对影响双锥天线电性能的各种尺寸参数的作以探讨，并且设计了一种可工作于0.8～3GHz的宽带双圆锥全向天线阵，给出了该天线的具体结构尺寸以及仿真后的VSWR数据曲线，E面，H面辐射方向图和频段内各频点的增益值，以及此天线在0.8～3GHz范围内的VSWR测试数据曲线，并进一步提出了一些设计此类天线的关键点。

Result］Like most of C3 plants, the diurnal changes curve of NPR of Lonicera japonica Thunb. showed double peaks, but there were time difference in reaching the peak value between the study and previous ones. The responding mathematical model of NPR to photosynthetic valid radiation could be described by three mathematic functions , such as logarithm, linearity and binomial,but binomial function was more precise than the others. Light saturation point of Lonicera japonica Thunb. was figured out by binomial equation deduced in the study, and light saturation point was 1 086.3 μmol/(m2·s).

结果］与多数其他C3植物一样，金银花净光合速率日变化曲线呈双峰型，但在具体达到峰值的时间上与前人的结果有差异；金银花净光合速率对光合有效辐射的响应可用对数、线性、二项式3种数学函数来描述，但以二项式描述更确切；根据前面得到的二项式方程，计算出了金银花的光饱和点为1 086.3 μmol/(m2·s)。
