Introduction

The radio interference of antennas and receiving systems is based on the "antenna" (invisible antenna-wireless receiving system) as the entry point to establish antennas and radio Electromagnetic compatibility standards for receiving systems, covering antennas, measurement sites and wireless receiving systems. GB/T (Z) 40602 "Radio Interference from Antennas and Receiving Systems" is intended to consist of four parts. ---Part 1.Indoor far-field measurement method for basic measurement of antenna pattern. The purpose is to specify the antenna radiation pattern in micro Measurement method for equal elevated far fields in anechoic chambers. ---Part 2.Basic measurement method of indoor plane near-field measurement of high-gain antenna pattern. The purpose is to specify high gain antennas Planar near-field scanning method is a method for measuring antenna pattern in a microwave anechoic chamber. ---Part 3.Site measurement and compression site performance confirmation method. The purpose is to specify the compact field shielding effectiveness and static field radiation characteristics. properties, phase characteristics and cross-polarization performance. ---Part 4.Test methods for electromagnetic compatibility of electronic equipment with integrated wireless modules in wireless receiving systems. The purpose is to provide for industrial use Electromagnetic compatibility test requirements and test methods for integrated wireless module electronic equipment such as industrial, scientific, medical, automotive, and household appliances. GB/T (Z) 40602 and GB/T 38889 together constitute the radio interference standard system for antennas and receiving systems. Radio interference from antennas and receiving systems Part 3.Site Measurement Compact Site Site Performance confirmation method

1 Scope

This document specifies the methods for confirming the performance of compaction sites, including general requirements, measurement systems, measurement methods, test reports and safety precautions. Protection requirements, etc. This document is suitable for confirmation of compact field performance in the operating frequency range of 0.6GHz~110GHz. For other frequency ranges, refer to use.

3 Terms and definitions

The following terms and definitions as defined in GB 8702-2014 and GB/T 12190-2021 apply to this document. 3.1 compactrange compactrange Using reflective surfaces or dielectric lenses combined with shielding and absorbing materials, the electromagnetic waves generated by the feed source are converted into plane waves at a short distance. Measurement site for free-space far-field conditions for quasi-plane wave irradiation. 3.2 quiet zone quiet zone It is usually an area where the device under test is placed in a compact field, where the clutter reflection of electromagnetic waves is controlled to the design level. 3.3 Taper Quantitatively describes an electromagnetic field distribution that decreases from the central axis to the edge, and the amplitude decreases from the central axis to the edge. Note 1.On the quiet zone field distribution curve, it refers to the difference between the maximum value and the minimum value of the curve. Note 2.Divided into amplitude taper and phase taper. 3.4 ripple It presents a random, nearly periodic, wave-like distribution unevenness. Note 1.Divided into amplitude ripple and phase ripple. Note 2.In the results of the quiet zone field distribution, the least squares method is used to fit the quadratic curve according to the original curve, and then the original curve and the quadratic curve are compared at different positions. Find the difference between lines, and use the largest difference as the ripple index. ......
