Antenna Radiation Pattern for ESP32-C3-Mini1 module

Hi,

I am using the ESP32-C3-Mini1 module with on board antenna and wanted to have following documentations -
  • Test data for following Antenna Performance test-list
    • Radiated power and sensitivity in shield box
    • VSWR/SWR measurement
    • The radiation pattern for the embedded antenna for 2.4GHz centre frequency.
    • Antenna efficiency: Test RSSI/range in LOS/NLOS

      I am more interested in knowing the 3D radiation pattern for gain vs angle in 3D and few planar cuts - so that I can decide the place ment and angle for the module inside the plastic enclosure.
      • documentation for the test firmware or if test data is available for the following RF stability tests
        • OTA Test
        • Frequency Drift at a particular set frequency over temperature
        • Power consistency for the wifi and BLE over a set channel/ frequency

          Can someone help me to point in a correct direction on where I can get this data?
