How can packet loss during ceramic antenna testing be avoided?

Packet loss during ceramic antenna testing can be mitigated through test environment optimization, connection and impedance verification, and improved antenna stability.

1. Keep the test environment away from metal objects and strong electromagnetic interference. Control temperature and humidity (25 °C ± 5 °C, 40%–60% RH), and avoid proximity of the human body.
2. Ensure firm, reliable connections between the antenna, connector, and transmission line with no cold solder joints. Maintain proper 50 Ω impedance matching(VSWR ≤ 2.0).
3. Select high-quality antennas (no cracks, intact solder pads), and preferably use semi-rigid coaxial cablesas test cables.
4. Adjust the relative orientation and angle between the reference antenna and the antenna under test to find the optimal polarization direction for signal transmission.
