UHF Antenna for Environmental Satellites

A successful test campaign has been performed over the UHF antenna. The UHF ANTENNA has been tested from the RF point of view and all required performances were compliant. The vibration test campaign can be considered successful since: No damage was detected during the overall vibration and shock (qualification levels) test sequence: No significant change in the response shape was detected between initial and final modal survey test. No significant frequency shifting (higher than 10%) and response amplitude variation (higher than 50%) are measured between each sine survey. Visual inspection performed along the test had not shown any damage Thermal test is considered successful as test temperatures have been achieved, obtaining good RF test results after the test. Power handling and PIM tests were also successful.
