Measured Efficiency & Gain Distribution
*Efficiency percentages represent average total radiation efficiency in a calibrated anechoic chamber environment.
Measurement Methodology
Testing was executed in a 3D fully anechoic chamber using a Vector Network Analyzer (VNA). The system underwent full two-port SOLT calibration, accounting for cable loss and fixture parasitics. Samples were evaluated across various ground plane configurations to ensure data repeatability.
- ✔ 1 MHz resolution for VSWR and S11 snapshots.
- ✔ Standard gain reference antennas for absolute realized gain.
Mid / High Frequency Results
The 1.71–2.69 GHz region represents the primary resonance. In this window, S11 values remain consistently below -10dB (VSWR < 2:1), ensuring maximum power transfer. High directivity in the E-plane supports robust indoor penetration for IoT gateways.
Integration & Optimization Checklist
PCB Layout
Maintain a 10-20mm keepout zone from large metallic objects. Keep the ground plane consistent.
Matching Network
Use small series/shunt LC elements (1–10 nH / 0.5–5 pF) close to the feed to fine-tune S11.
Field Validation
Verify RSRP/RSSI and throughput against lab baselines in the final device enclosure.
