FCC ID: A3LSMS918U Power Density Simulation Report Revision A November 07, 2022 SAMSUNG ELECTRONICS 1. Simulation methodology for Power Density (PD) 1.1 Simulation tool 1.1.1 Tool description For the simulation approach to calculating power density (PD) evaluation for mobile phone with mmWave antenna modules, ANSYS Electromagnetics suite version 2022.R1 (HFSS) is used. ANSYS HFSS is one of several commercial tools for 3D full-wave electromagnetic simulation used for antenna and RF structure design of high frequency component. ANSYS Electromagnetics suite version 2022.R1 (HFSS) is implemented based on Finite Element Method (FEM), which operates in the frequency domain. 1.1.2 Mesh and Convergence criteria To solve the PD analysis using FEM, volume area containing simulated objects should be subdivided into electrically small parts that are called finite elements as the unknown functions. To subdivide system, the adaptive mesh technique in ANSYS Electromagnetics suite version 2022.R1 (HFSS) is used. ANSYS Electromagnetics suite version 2022.R1 (HFSS) starts to refine the initial mesh based on wavelength and calculate the error to iterative process for adaptive mesh refinement. The determination parameter of the number of iteration in ANSYS Electromagnetics suite version 2022.R1 (HFSS) is defined as convergence criteria, delta S, and the iterative adaptive mesh process repeats until the delta S is met. In ANSYS Electromagnetics suite version 2022.R1 (HFSS), the accuracy of converged results depends on the delta S. Figure 1 is an example of adaptive mesh of the device (cross-section of top view). Figure 1 Example of the adaptive mesh technique (Top view) 1.1.3 Power density calculation After solving 3D full-wave electromagnetic simulation, various kinds of physical quantities can be obtained. To calculate PD evaluation, two physical quantities, an electric field (E ��⃗ ) and a magnetic field (H ��⃗ ) are needed. The actual consumption power can be expressed as the real term of the Poynting vector (S �⃗ ) from the cross product of E ��⃗ and complex conjugation of H ��⃗ as shown below: 〈 S �⃗ 〉 =Re� 1 2 E ��⃗ × H ��⃗ ∗ � 〈 S �⃗ 〉 can be expressed as point power density based on a peak value of each spatial point on mesh grids, and obtained directly from ANSYS Electromagnetics suite version 2022.R1 (HFSS). From the point power density 〈 S �⃗ 〉 , the spatial-averaged power density (PD 푎푎푎푎 ) on an evaluated area (A) can be derived as shown below: PD 푎푎푎푎 = 1 퐴퐴 � 〈 S �⃗ 〉 ∙푑푑푑푑= 퐴퐴 1 2퐴퐴 푎푎푎푎 � ‖ 푅푅푅푅 { 퐸퐸퐸퐸퐻퐻 ∗ }‖ 퐴퐴 푎푎푎푎 푑푑퐴퐴 , where the spatial-averaged power density (PD 푎푎푎푎 ) is total power density value considering on x, y and z components of point power density 〈 S �⃗ 〉 and the evaluated area (A) is 4cm 2 . 1.2 Simulation setup 1.2.1 3D modeling Figure 2 shows the simulation model which is mounted two mmWave antenna modules. The simulation modeling includes most of the entire structure of device itself such as PCB, metal frame, battery, cables, and legacy antennas as well as mmWave antenna modules called as Ant M and Ant N. The modeling contains the entire EUT to enable a Smart transmit GEN2, as well. Ant M is placed on the left side and antennas are facing the back side, and Ant N is placed on the right side and antennas are facing the right side of the device. Figure 2 Simulation model which is mounted two mmWave antenna modules 1.2.2 PD evaluation planes Table 1 shows the PD evaluation planes for each mmWave antenna module and Figure 3 shows the PD evaluation planes and truncation area of the simulation model to find worst case of beamforming cases. Please note that the “right” and “left” edge of mentioned in this report are defined from the perspective of looking at the device from the front side. Table 1. PD evaluation planes Module Front Back Left From Front View Right From Front View To p Bottom S1 S2 S3 S4 S5 S6 Ant M O O O O O O Ant N O O O O O O Figure 3. PD evaluation planes 1.2.3 Boundary condition To simulate electromagnetic tool based on FEM, the boundary condition allows electromagnetic waves to be electrically open at the boundary and radiated far away without reflection. ANSYS Electromagnetics suite version 2022.R1 (HFSS) can support the absorbing boundary condition (ABC) for radiation boundary and make normally a quarter wave length from the radiating structure. In this report, to cover all beamforming cases of mmWave antenna modules, 40 mm spacing from the device for each surfaces were adopted. This distance is sufficiently large enough for “Qualcomm MG script” to extract valid E- and H-fields from all adjacent exposure surfaces of the EUT. 1.2.4 Source excitation condition The number of antenna ports of ANT M and ANT N for source excitation are the same. The antenna port of ANT M and N is divided into 10 ports for n261 and n258 1 x 5 patch array antennas, 10 ports for n260 1 x 5 patch array antennas. In the 10 ports included in each patch antenna, 5 ports are divided into vertical polarization feeding, and the other 5 ports are divided into horizontal polarization feeding. Figure 4 shows the ANT M module structure and surrounding structure. The ANT M module is encrypted in the ANSYS Electromagnetics suite (HFSS) and can only check the feeding position. Figure 4. mmWave module (ANT M) After finishing 3D full wave electromagnetic simulation of modeling structure, the magnitude and phase information can be loaded for each port by using “Edit Sources” function in ANSYS Electromagnetics suite (HFSS). Figure 5 shows an example of antenna port excitations. Figure 5. An example of port excitation (ANT N) Since ANSYS Electromagnetics suite (HFSS) uses FEM solver based on frequency domain analysis method, the input source for the port excitation applies sinusoidal waveform for each frequency. 1.2.5 Condition of simulation completion The simulation completion condition of ANSYS Electromagnetics suite (HFSS) is defined as delta S. The ANSYS Electromagnetics suite (HFSS) calculates …
