Introduction

This section describes the Antenna Calibration Test Site (CALTS) validation procedure for antenna calibration from 5MHz to 18GHz. Correct See the GB/T 6113.106-2018 for the antenna calibration procedure. For the ground reflection suppression problem of 30MHz~200MHz, the main function of the reflection ground plane is to match the dipole antenna and double The cone antenna and the composite antenna are calibrated, and the pattern of the H-plane in these bands is uniform in this frequency band. For dipole antennas, freedom The spatial antenna coefficient Fa can be measured by measurement in a free space environment of.200 MHz or more. Due to the reduction of the object around the antenna Shooting is very difficult, especially from the ground, so a flat metal ground plane is used to ensure the reproducibility of the measurement results and can be reversed The signal is accurately eliminated by mathematical calculations. Appendix A gives the requirements for constructing CALTS, and Chapter 4 gives the technical specifications for CALTS and the Reference Test Site (REFTS). And confirmation procedures. The most accurate way to confirm CALTS is to use a computable dipole antenna as the basis for this part of the validation process. Appendix B gives the design principles for computable antennas. Appendix C and Appendix D give the theory and method for calculating site insertion loss (SIL). Chapter 5 ~ Chapter 7 gives confirmation procedures for other antenna calibration sites. For antenna calibration methods that use ground reflection, To use CALTS. Table 1 summarizes the site validation methods that correspond to the antenna calibration methods in GB/T 6113.106-2018. All site validation methods involve SIL between the two antennas. It is vital that the effectiveness of the site itself is not To the excessive influence of antenna support reflection, A.3 gives the relevant guidelines.

The effect is less than 0.5 dB compared to the theoretical value. For SAC, it is important that the acceptance criterion of 1 dB includes not only the uncertainty introduced by wall reflection, but also Including the uncertainty introduced by reflections such as antenna towers and cables.

1 Scope

This part of GB/T 6113 specifies the antenna calibration in the frequency range of 5MHz~18GHz according to GB/T 6113.106-2018. The quasi-calibration site requirements also stipulate the conformity test in the frequency range of 30MHz~1GHz according to GB/T 6113.104-2016. The reference test site (REFTS) requirements confirmed by the site (COMTS). Note. According to IEC Guide 107, CISPR 16-1-5 is the basic electromagnetic compatibility (EMC) standard used by the IEC product committee. As IEC Guide 107 The product committee is responsible for determining the applicability of the EMC standard. CISPR and its subcommittees (corresponding to domestic SAC/TC79 technology The committee and its subcommittees work with these product committees to assess the value of specific trials for their specific products. Product committee Will correspond to the relevant domestic product technical committee. CISPR16-1-1[1] and GB/T 6113.104-2016 give specifications for measuring equipment, CISPR16-4[3] gives relevant uncertainties. More detailed information and background information on the scale, which helps to assess the measurement uncertainty during antenna calibration and site validation.
