【摘要】 天线参数量值的准确溯源情况与天线产品交付、天线测量系统的验收等息息相关。由于在工程测量中,通常采用标准天线法(比较法)来测量,因此需要先研究标准天线及其量值溯源技术。本文主要介绍了两类天线的计量技术。这包括:1) 1GHz以下的线结构类标准天线的量值溯源方法和对应的计量装置;2) 1GHz以上的标准增益喇叭天线的计量方法和计量装置。前者天线系数和天线增益的测量扩展不确定度可达0.15 dB,而后者标准增益喇叭天线的增益测量扩展不确定度可小于0.06 dB。更多还原

【Abstract】 The accurate traceability of antenna parameter values is closely related to the delivery of antenna products and the acceptance of antenna measurement systems.Since standard antenna method(comparison method) is commonly used in engineering measurement,it is necessary to study the standard antenna and its traceability technique.This article mainly introduces two types of calibration techniques for antennas,including:1) the traceability method and corresponding calibration equipment for line structure standard antennas below 1 GHz,and 2) the calibration method and equipment for standard gain horn antennas above 1 GHz.The measurement uncertainty for antenna factor and gain of the former can reach 0.15 dB,while the uncertainty for gain measurement of the latter can be less than 0.06 dB.更多还原
