What is the role of insulation resistance in antennas and connectors?

Insulation resistance is a key parameter used to evaluate the performance of insulating materials. Its main functions are as follows:

1. Evaluating insulation quality

Higher insulation resistance indicates lower leakage current and more reliable electrical isolation performance.

2. Preventing leakage and short circuits

It ensures that current flows only along the intended conductive paths, preventing leakage to the housing or adjacent contacts and eliminating short-circuit risks.

3. Ensuring electrical safety

It helps prevent energized housings, thereby reducing the risk of electric shock and improving user safety.

4. Indicating long-term reliability

Under harsh conditions such as high temperature, humidity, and aging, changes in insulation resistance reflect degradation of insulation performance and help predict potential product failure risks.
