Comparison of change in received signal strength for all measurements.
| Antenna type | Scenario | In the absence of target | In the presence of target | |
| Single patch antenna | RSS at 0° (dB) | −59 | −75 | 16 | RSS at 20° (dB) | −61 | −66 | 5 | Linear array antenna | RSS at 0° (dB) | −55 | −75 | 20 | RSS at 20° (dB) | −66 | −80 | 14 |
