* Antenna OTA Passive Testing Passive S-parameter testing environment: Description: 1. For this test, the latest optimized PCB was used. The RF Cable length for the test was 7 cm; for actual usage scenarios, a USB Cable was included. 2. ANT 1 is the antenna at the bottom of the PCB, and ANT2 is the antenna on the left side (Type C USB port side) of the PCB. Test conclusion: 1. The return loss (S11) of ANT 1 in the 2.4GHz band was less than -14.5dB, and in the 5GHz bands was less than -9.5dB. 2. The return loss (S11) of ANT 2 in the 2.4GHz band was less than -19.8dB, and in the 5GHz bands was less than -6.6dB. 3. The isolation degree (S21) of ANT0 and ANT2 in the 2.4GHz band was better than -15.0dB, and in the 5GHz bands was better than -25.5dB. 4. The efficiency of ANT 1 in the 2.4GHz band was approximately 53%, and in the 5GHz bands was greater than 58%. 5. The efficiency of ANT2 in the 2.4GHz band was between 56% and 61%, greater than 51% in the 5150GHz - 5650GHz frequency band, and greater than 60% on average in the 5700GHz - 5850GHz high-frequency band. The efficiency was between 38% and 43% in the 38% - 43% range in the 5700GHz - 5850GHz frequency band. * Antenna OTA Passive Testing OTA testing environment: * Antenna OTA Passive Testing S11 return loss parameters - ANT1: 2.4GHz and 5GHz bands Antenna OTA Passive Testing S11 return loss parameters - ANT2: 2.4GHz and 5GHz bands Isolation: S12 or S21 Return Loss Parameters - ANT1 & ANT2: 2.4GHz and 5GHz Bands Antenna OTA Passive Testing * Antenna OTA Passive Parameter Comparison (Efficiency, Gain, Radiation Pattern) Efficiency, Gain: 2.4GHz Band ANT1 Efficiency, Gain: 5GHz Band ANT1 Antenna OTA Passive Parameter Comparison (Efficiency, Gain, Radiation Pattern) * Antenna OTA Passive Parameter Comparison (Efficiency, Gain, Radiation Pattern) Efficiency, Gain: 2.4GHz Band ANT2 Antenna OTA Passive Parameter Comparison (Efficiency, Gain, Radiation Pattern) Efficiency, Gain: 5GHz Band ANT2 * Antenna OTA Passive Parameter Comparison (Efficiency, Gain, Radiation Pattern) Directional pattern: 2.4GHz Band ANT1 E13D E2 H Antenna OTA Passive Parameter Comparison (Efficiency, Gain, Radiation Pattern) Directional pattern: 5GHz Band ANT1 E13D E2 H * Antenna OTA Passive Parameter Comparison (Efficiency, Gain, Radiation Pattern) Directional pattern: 2.4GHz Band ANT2 E13D E2 H * Antenna OTA Passive Parameter Comparison (Efficiency, Gain, Radiation Pattern) Directional pattern: 5GHz Band ANT2 E13D E2 H Antenna Size
