C63.19 SC8 WG3 meeting, March 26, 2007 Calibration values for dipole validations at new RF probe separation distance of 1.5cm PINS-C item 5.k Jagadish Nadakuduti EME Research Engineer, Motorola, Inc. C63.19 SC8 WG3 meeting, March 28, 2006

C63.19 SC8 WG3 meeting, March 26, 2007 Outline Background –C Amendment: Change the RF measurement position from bottom of probe element to the center of element and change the test distance from 10mm to 15mm FDTD simulations Updated Table 4.2 and Table D.4 Measurements Conclusion

C63.19 SC8 WG3 meeting, March 26, 2007 Background: PINS-C item 5.k The RF probe separation distance is 15 mm and the calibration values in table 4.2 were made at 10 mm. These calculations need to be redone at 15 mm distance. 15 mm

C63.19 SC8 WG3 meeting, March 26, 2007 FDTD simulations: Results at 10 mm Created FDTD models as specified in “D Dipole validation theoretical modeling”.

C63.19 SC8 WG3 meeting, March 26, 2007 FDTD simulations: Results at 10 mm contd. CW peak E- and H-field values taken from table D-4 are converted into RMS values. These values are incorporated into Table 4.2. Table 4.2 – Illustrated dipole calculated values (existing and new simulation results) “D Dipole validation theoretical modeling” section describes simulations for ‘thick dipoles’ and has no information on modeling parameters for ‘planar dipoles’. The relatively high difference between values specified in table 4.2 and those from new simulations in case of ‘planar dipoles’ might be because of using different simulation parameters. DipoleFreq.

C63.19 SC8 WG3 meeting, March 26, 2007 Conclusion ‘Planar dipole’ FDTD simulations need to be repeated with the correct parameters. The following sections in C need to be updated with calibration values at 15 mm distance –In Section 4.4: Table 4.2 –In Annex D: Table D.4 Figures D.3 - D.6, D.10 Equations D.1 & D.2 Include ‘Planar dipole’ simulation parameters in section ‘D Dipole validation theoretical modeling’. All of the above tasks can be completed in a time frame of 1-2 months.
