Simulated Self-user Shadowing for Mobile Phone Antennas at 28 GHz and at 60 GHz

Tietoaineisto

Description

The purpose of this dataset is to complement our EuCAP 2019 conference publication "Self-user shadowing effects of millimeter-wave mobile phone antennas in a browsing mode" by M. Heino, C. Icheln, and K. Haneda (DOI: tba). This dataset contains the 3-D surface meshes of the two human body models used in the above publication. One body model holds the mobile phone with one hand (vertically, "OneHand") and the other one with both hands (horizontally, "TwoHand"). The body models were exported from MakeHuman (http://www.makehumancommunity.org/), the actual body postures were then created with Blender 3D creation suite (https://www.blender.org/), and these final body models were exported in OBJ format (a generic geometry definition file format). Then these were imported to CST Studio Suite (www.cst.com) to simulate the realised-gain patterns of the dual-polarised mobile phone antenna. The material properties of the human body model are described in detail in the above publication. Also the antenna design with one vertical feed port and one horizontal feed port is described in detail within the above publication (see Fig. 3) and is not part of this dataset. (Note that "port #1" in Fig. 3 of the publication is the vertical antenna port for the one-hand case, but the horizontally antenna port in the two-hand case.) This dataset also contains the polarimetric, directional, complex-valued (real, imaginary) realised-gain patterns, seperately for 28 GHz and for 60 GHz, in 1-degree resolution in both phi and theta directions. The patterns are seperately given for the vertical ("VPolPatch")and the horizontal feed port ("HPolPatch"). The 2-D pattern cuts presented in the above publication are subsets of these 3-D patterns. The format of the eight ascii files {xxGHzStandingyyHandzzPolPatch.txt} is a follows: 1st column: Theta angle in degrees 2nd column: Phi angle in degrees 3rd column: real part of Gain, theta component, in dBi 4th column: imaginary part of Gain, theta component, in dBi 5th column: real part of Gain, phi component, in dBi 6th column: imaginary part of Gain, phi component, in dBi where xx is "28" or "60" (GHz), yy is "One" or "Two" (-hand grip), and zz is "H" or "V" (-pol. antenna port), as described above. The spherical coordinate system is used in accordance to the IEEE-standard spherical coordinate system. The underlying Cartesian coordinate system is shown in the two attached preview (PNG) image files for both human body models, where the z-axis (theta=0 degrees) points to the directions of the head of the human, the x-axis (phi=0 degrees) towards the left side of the human, and the y-axis toward the back of the human.
