Introduction

The radio interference of the antenna and the receiving system is based on the "antenna" (invisible antenna-wireless receiving system) as the entry point to establish the antenna and radio The electromagnetic compatibility standard of the receiving system covers antennas, measurement sites and wireless receiving systems.

GB/T 40602 "Radio Interference from Antennas and Receiving Systems" is intended to consist of the following parts.

---Part 1: Basic indoor far-field measurement method of antenna pattern. The purpose is to specify the antenna radiation pattern (below Referred to as the radiation pattern) is a method of measuring the elevated far field in a microwave anechoic chamber.

---Part 2: Basic measurement method of indoor planar near-field measurement of high-gain antenna pattern. The purpose is to specify high-gain antennas The planar near-field scanning method is a method for measuring the antenna pattern in a microwave anechoic chamber.

---Part 3: Field measurement method for confirming the performance of the compact field. The purpose is to specify the tight field shielding effectiveness, static field radiation characteristics Measurement methods for performance, phase characteristics, and cross-polarization performance.

---Part 4: The electromagnetic compatibility test method of the integrated radio module electronic equipment of the wireless receiving system. The purpose is to provide for EMC testing requirements and testing methods for electronic equipment with integrated wireless modules such as industrial, scientific, medical, automotive, and household appliances.

The above four parts and the previously published GB/T 38889-2020 on vehicle antennas and systems together form the antenna and receiving system. A unified radio interference standard system.
