Abstract-Characteristic modes of a spherical shell are found analytically as spherical harmonics normalized to radiate unitary power and to fulfill specific boundary conditions. The presented closed-form formulas lead to a proposal of precise synthetic benchmarks which can be utilized to validate the method of moments matrix or performance of characteristic mode decomposition. Dependence on the mesh size, electrical size and other parameters can systematically be studied, including the performance of various mode tracking algorithms. A noticeable advantage is the independence on feeding models. Both theoretical and numerical aspects of characteristic mode decomposition are discussed and illustrated by examples. The performance of state-of-the-art commercial simulators and academic packages having been investigated, we can conclude that all contemporary implementations are capable of identifying the first dominant modes while having severe difficulties with higher-order modes. Surprisingly poor performance of the tracking routines is observed notwithstanding the recent ambitious development.Index Terms-Eigenvalues and eigenfunctions, convergence of numerical methods, numerical analysis, numerical stability.

“…The TCM also helps to find the contribution of each characteristic mode on the overall radiation [31]. Depending on the design of the coupling element, its location with respect to the chassis, and the feeding configuration, one can selectively excite separate wavemodes [30], [32], or maximize the number of modes to excite.…”

Since the beginning of the century, it was gradually understood how the metallic chassis of a mobile handset can be utilized as the main radiating element of a mobile terminal antenna. After a decade of research, the use of inherently non-resonant coupling elements has become a competitive antenna choice in today's multi-standard mobile handsets. This paper combines the use of some helpful computational tools to synthesize a mobile handset antenna capable of satisfying the requirements of today's mobile communications standards at 0.7-0.96 GHz and 1.71-3.6 GHz with good performance. We also demonstrate how the CCE concept can be extended beyond mobile communications.
