5G Omni Antenna Test

Physical test of 5G full-band omnidirectional fiberglass reinforced plastic antenna

In the current era of rapid popularization of 5G technology, antenna performance directly affects network coverage and user experience. To verify the actual performance of the 5G full-band and omnidirectional fiberglass reinforced plastic antenna, we carried out professional tests.

I. Test Preparation

Professional equipment such as vector network analyzers and microwave anechoic chambers were selected for testing in an electromagnetic shielded laboratory with a temperature of 25±2℃ and a humidity of 45% - 55% to ensure the accuracy of the data.

Ii. Core Test Items

Full frequency band coverage: Through a vector network analyzer, sweep the 5G full frequency band (low frequency band 300MHz - 1GHz, mid frequency band 1GHz - 6GHz, high frequency band 24.25GHz - 52.6GHz), and record the return loss and standing wave ratio.

Omnidirectional radiation: In a microwave anechoic chamber, with the antenna as the center, points are set at intervals of 10° in the horizontal direction to measure the signal strength in all directions and draw the radiation pattern.

Gain and efficiency: Use the comparison method to compare the received power with that of the standard antenna and calculate the gain. Evaluate the radiation efficiency in combination with the input and output power.

Environmental adaptability: Simulate a high temperature of 70℃, a low temperature of -40℃, a humidity of 95%, as well as salt spray and sand dust environments to test the stability of antenna performance.

Iii. Key Test Results

Tests show that the return loss within the full frequency band is less than -10dB and the standing wave ratio is less than 2, achieving good signal transmission. The difference in signal intensity in the horizontal direction is controlled within ±1dB, and the omnidirectional radiation characteristics are excellent. The mid-band gain is 3dBi, the high-frequency band gain is 5dBi, and the radiation efficiency exceeds 85%. After being tested in harsh environments, the performance indicators fluctuate little and it has strong environmental adaptability.

Iv. Conclusion

This test confirmed that the 5G full-band and omnidirectional fiberglass reinforced plastic antenna performs outstandingly in terms of frequency band coverage, radiation characteristics, gain efficiency and environmental adaptability, providing strong support for the stable operation of 5G networks and having broad application prospects.
