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

The purpose of this dataset is to supplement the data presented in our conference publication "Self-user shadowing effects of millimeter-wave mobile phone antennas in a browsing mode" at EuCAP 2019 (see https://ieeexplore.ieee.org/document/8739947).

This dataset contains the 3-D surface meshes of the two numeric human body models used in the above publication. One body model holds the mobile phone with one hand (vertically, "OneHand") and the other body model with both hands (horizontally, "TwoHand"). The body models were initially 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 models were imported into CST Studio Suite (http://www.cst.com) in order to simulate the 3-D realised-gain patterns of the antenna. The material properties of the human body model used in the simlations are described in detail in the above publication. Also the dual-polarised mobile-phone 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 denotes the vertical antenna port for the one-hand case, while "port #1" denotes the horizontally antenna port in the two-hand case.)

This dataset also contains the simulated 3-D 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 (in Figs. 5-11) are subsets of the 3-D patterns in this dataset.

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.
