Accurate and precise E‐field measurement for 2G and 3G networks based on IEEE Std. 1309‐2013

This article elaborates the theoretical and measurement technique to evaluate precise and accurate electric (E)-field strength for frequency range 0.8-2.4 GHz (2G and 3G communication spectrum). The E-field using a probe is precisely measured inside an indigenously designed transverse electromagnetic (TEM) cell as per IEEE Std. 1309-2013. Key parameters for precise E- field measurement are explicated with their measurement results such as probe linearity, field distortion, and mismatch losses. E-field strength of probe has been reported 9.91 V/m with an expanded uncertainty (k approximate to 2) of +/- 0.58 V/m for +18 dBm fed power at 915 MHz frequency.
