With the pigtail on -y axis (Φ 270°) passive antenna performance was measured by VNA and OTA chamber system. The measurement was done in the configuraƟon representaƟve on how it would be with intended end user. Commercial test soŌware: WaveStudio25.1.0 Test Procedure: (Passive Antenna Measurement): 1. Mount the Device Under Test (DUT) on the supporting pole at the center of the anechoic chamber. 2. Connect the DUT antenna port to the measurement system using a coaxial cable at the transmiƩer side of the chamber. 3. Close the chamber door to eliminate external signal interference during measurement. 4. Launch the antenna measurement system, configure the required test parameters (e.g., frequency points or rotaƟon angles), and import the frequency list for testing.
