Test Result: Return Loss
Ant1
A network analyzer plot showing Return Loss for Ant1. The X-axis ranges from 2 GHz to 8 GHz, and the Y-axis ranges from -50 dB to 50 dB. Key markers indicate values such as -12.480 dB at 2.400 GHz, -13.915 dB at 2.450 GHz, and -12.689 dB at 2.500 GHz.
Ant2
A network analyzer plot showing Return Loss for Ant2. The X-axis ranges from 2 GHz to 8 GHz, and the Y-axis ranges from -50 dB to 50 dB. Key markers indicate values such as -14.113 dB at 2.400 GHz, -13.604 dB at 2.450 GHz, and -12.920 dB at 2.500 GHz.
Ant3
A network analyzer plot showing Return Loss for Ant3. The X-axis ranges from 5 GHz to 6 GHz, and the Y-axis ranges from -50 dB to 50 dB. Key markers indicate values such as -21.029 dB at 5.150 GHz, -15.789 dB at 5.500 GHz, -25.035 dB at 5.850 GHz, and -17.342 dB at 5.925 GHz.
Ant4
A network analyzer plot showing Return Loss for Ant4. The X-axis ranges from 5 GHz to 6 GHz, and the Y-axis ranges from -50 dB to 50 dB. Key markers indicate values such as -15.775 dB at 5.150 GHz, -18.926 dB at 5.500 GHz, -20.421 dB at 5.850 GHz, and -21.394 dB at 5.925 GHz.
2D Radiation Patterns
Ant1
Polar plots showing the 2D radiation patterns for Ant1. For the XY-Plane, XZ-Plane, and YZ-Plane, patterns are displayed for 2400 MHz (blue line), 2450 MHz (green line), and 2500 MHz (red line). The radial axis represents gain in dBi, with markings at 0, -5, -10, -15, -20, -25, -30, -35, -40, -45, -50. The angular axis represents direction in degrees (0, 45, 90, 135, 180, 225, 270, 315).
Ant2
Polar plots showing the 2D radiation patterns for Ant2. Similar to Ant1, patterns are displayed for the XY-Plane, XZ-Plane, and YZ-Plane for 2400 MHz (blue line), 2450 MHz (green line), and 2500 MHz (red line). The radial axis represents gain in dBi, and the angular axis represents direction in degrees.
Ant3
Polar plots showing the 2D radiation patterns for Ant3. For the XZ-Plane H+V, YZ-Plane H+V, and XY-Plane H+V, patterns are displayed for 5150 MHz (red line), 5500 MHz (green line), and 5925 MHz (blue line). The radial axis represents gain in dBi, with markings at 0, -5, -10, -15, -20, -25, -30, -35, -40, -45, -50. The angular axis represents direction in degrees (indicated by labels like +X (90), -X (270), +Y (90), -Y (270), and (180)).
Ant4
Polar plots showing the 2D radiation patterns for Ant4. Similar to Ant3, patterns are displayed for the XZ-Plane H+V, YZ-Plane H+V, and XY-Plane H+V for 5150 MHz (red line), 5500 MHz (green line), and 5925 MHz (blue line). The radial axis represents gain in dBi, and the angular axis represents direction in degrees.
