SAR COMPLIANCE TESTING OF CARD ACCESS MODEL MHI-CAWCB500 5.15 TO 5.35 GHz CARDBUS CARD INSERTED INTO A LAPTOP COMPUTER July 18, 2001 Submitted to: Mr. Nathan Mueller Design Engineer Card Access 71 North 490 West American Fork, UT 84003 Submitted by: Om P. Gandhi Professor of Electrical Engineering University of Utah 50 S Central Campus Dr., Rm. 3280 Salt Lake City, UT 84112-9206 SAR COMPLIANCE TESTING OF CARD ACCESS MODEL MHI-CAWCB500 5.15 TO 5.35 GHz CARDBUS CARD INSERTED INTO A LAPTOP COMPUTER I. Introduction The U.S. Federal Communications Commission (FCC) has adopted limits of human exposure to RF emissions from mobile and portable devices that are regulated by the FCC [1]. The FCC has also issued Supplement C (Edition 97-01) to OET Bulletin 65 [2] and a more recent version of the same [3] defining both the measurement and the computational procedures that should be followed for evaluating compliance of mobile and portable devices with FCC limits for human exposure to radiofrequency emissions. We have used both the measurement and computational procedures for SAR compliance testing of the Card Access CardBus card (FCC ID: MHI-CAWCB500) inserted into a laptop computer. A photograph of the unit with the CardBus card inserted into the laptop computer is given in Fig. 1. A picture of the Model CAWCB500 CardBus card placed on the laptop is given in Fig. 2. For spatial diversity, the CardBus card uses two 5 GHz Side Stem Antennas each of geometry and dimensions given in Fig. 3. The antenna feed of width 1.75 mm and length 1.8 mm shown in Fig. 3 is mounted on a substrate of thickness 10 mils (0.25 mm) and dielectric constant 4.25. The two antennas are placed with a center-to-center spacing of 24.23 mm over a ground plane of width 43 mm and approximate length 45 mm. At any given time, only one of the two antennas is working either for the transmission or the reception mode. The Card Access Model CAWCB500 CardBus card operates with a transmit power to up to 16 dBm (40 mW). Since the wireless PC may possibly be placed on a user's lap where the RF antennas would be the closest to the body, a planar phantom model was used both for SAR calculations as well as for SAR measurements. 2 II. Computation of SAR Distributions The Finite Difference Time-Domain Method One of the most successful and versatile methods for SAR calculations is the finite-difference time-domain (FDTD) method. This method was first proposed by Yee [4] and later developed by Taflove and colleagues [5-7], Holland [8], and Kunz and Lee [9]. This method has been extensively used for calculations of the distributions of electromagnetic (EM) fields and SARs in anatomically-based models of the human body for whole-body or partial-body exposures due to far-field or near-field irradiation conditions [10, 11]. In this method, the time-dependent Maxwell's curl equations ∇×E=-μ ∂H ∂t ,∇×H=σE+ε ∂E ∂t (1) are implemented for a lattice of sub volumes or "cells" that may be cubical or parallelepiped with different dimensions δ x , δ y , and δ z in x-, y-, or z-directions, respectively. The components of E and H are positioned about each of the cells as shown in Fig. 4 and calculated alternately with half-time steps where the time step δt = δ/2c where δ is the smallest of the dimensions used for each of the cells and c is the maximum phase velocity of the fields in the modeled space. Since some of the modeled volume is air, c corresponds to the velocity of EM waves in air. The details of the method are given in several of the above referenced publications [4-9] and will, therefore, not be repeated here. In the FDTD method, it is necessary to represent not only the scatterer/absorber such as the human body or a part thereof, but also any near-field sources/s such as the Side Stem Antenna of Fig. 3 mounted into a laptop computer. Since the SAR distribution is critically dependent on the antenna geometry and its placement vis à vis the lossy planar model simulant of the human lap, this region was modeled with an FDTD cell size of 0.6 × 0.6 × 0.6 mm. This choice of the cell dimensions allowed a proper 3 representation of the stem antenna height (3.6 mm), its width (1.75 or nearly 1.8 mm), the top loading circular hat (diameter 8.4 mm) and the antenna feed of width 1.75 or 1.8 mm and length 1.8 mm), the ground plane of dimensions (42 × 74.4 mm) and the separation between the bottom of the ground plane to the top of the lap-simulant model of 1.08 cm (18 cells). For SAR calculations, we have assumed a planar muscle-simulant lossy phantom at a distance of 1.08 cm below the CardBus card ground plane to account for a part of the thickness of the PC keyboard. For this planar model of dimensions 13.8 × 10.8 × 5.4 cm modeled by 230 × 180 × 90 cells (of dimension 0.6 mm), we have used muscle-simulant dielectric properties of ε r = 49.22 and conductivity σ = 4.32 S/m taken from the FCC website [www.fcc.gov/fcc-bin/dielec.sh]. Similar to the FDTD cell size used for modeling of the antenna, this planar tissue-simulant is also modeled by a cell size of 0.6 mm. A graphical representation of the SAR distributions calculated for the surface layer and for three additional layers at depths of 3, 6, and 9 mm are shown in Fig. 5, respectively. For all of these calculations, the antenna excited for a total radiated power of 16 dBm (40 mW) is assumed to be in the upper right hand corner which explains the high SARs for the phantom underneath. The calculated power absorbed by the entire phantom is 8.20 mW (20.5% of the conducted power) and the peak 1-g SAR is 0.176 W/kg. For SAR calculations, we have also used a second tissue-simulant phantom which is a proper representation of the rectangular box phantom used for experimental SAR measurements (see Fig. 7). This box phantom described in detail in Section V uses an acrylic base of thickness 6.35 mm and dielectric constant ε r = 2.56. For the present calculations, we have represented this base by 10 layers of FDTD cells thu…
