“…The magnetic field components H θ | n+0.5 i+0.5,0,k+0.5 , H θ | n+0.5 i+0.5,J,k+0.5 are not updated as they are not needed at all and the electric fields E φ | n i,0,k+0.5 , E φ | n i,J,k+0.5 , although not singular, are kept zero. The remaining field components follow the standard formulas (1)- (6).…”

In this paper, the spherical-coordinate finite-difference time-domain (FDTD) method is applied to numerical analysis of phased array of monopoles distributed over a sphere. Outer boundary of the given problem is modeled by accurate spherical-coordinate anisotropic perfectly matched layer (PML). The problem of increased cell aspect ratio near the sphere poles causing degradation of results is solved by dispersion optimization through artificial anisotropy. The accuracy of the approach is verified by comparing a model case with an exact solution. Finally, radiation patterns obtained by frequency-domain nearto-far-field transform and s-parameters of the array elements are presented and validated by comparing with measurement data.

“…The 120-element constellation with conformal circular patches was mentioned in [5]. Another version of spherical array, with turnstile antennas as array elements, is numerically analyzed and discussed in [6]. In the measurement system described in [7], 32 dual-polarized rectangular microstrip patches are utilized.…”

“…Rectangular patches are used in [1,2], whereas circular patches are utilized in [3]. Other types of array elements include crossed dipoles [4,5], spiral antennas presented in [6], and finally [7] describes a spherical array with annular ring antennas as elements. Distribution of the elements across the surface of the sphere is discussed in [8,9].…”

-Three types of spherical arrays for use in wireless communication research are presented. First, a spherical array of 32 monopoles with beam steering in arbitrary direction and with arbitrary polarization is described. Next, a spherical array with 16 quad-ridged open-flared horns is introduced, offering better wideband performance and easier beam steering. Finally, a multi-probe setup for over-theair testing of multiple-input multiple-output mobile devices is presented, being essentially a spherical array with inward radiation.
