摘要

标准喇叭天线广泛应用于收发天线的天线测量装置中，为了最终计算被测天线的增益，需要知道其绝对增益。然而，这些喇叭天线的增益参数通常不完全由制造商提供，因此应该在我们自己的设置中测量。本文旨在提出一种基于弗里斯公式的实验方法，通过该方法可以获得工作在50 GHz至75 GHz范围内的标准喇叭天线的增益。在我们的常规测试中使用了覆盖50 GHz至325 GHz的所有标准喇叭的测量增益参数，并证明了其可靠性，从而提高了我们的天线测量设置中计算的AUT增益的正确性。

Gain Acquisition of a Standard Horn Antenna Through Experimental Method

Standard horn antennas are widely used in antenna measurement setups for transceiver antennas application, whose absolute gain is necessary to be known in order to finally calculate the gain of antennas under test (AUT). Yet, the gain parameters of these horn antennas are often not provided completely by manufacturers and thus should be measured in our own setup. This paper aims to present an Friis-formula-based experimental method by which the gain of a standard horn antenna operating from 50 GHz to 75 GHz can be acquired. The measured gain parameters of all the standard horns covering the 50 GHz to 325 GHz has been used in our regular tests and proved to be convincible, the correctness of the calculated AUT gain in our antenna measurement setup has therefore been improved.
