| Summary: | The objective of this paper is to study the radiation
performance of mobile handsets antenna by using the
hybrid method between the Finite-Element Method
(FEM) and the Finite Difference Time Domain
(FDTD), as applied to computational electromagnetic
studies, e.g. antenna scattering modelling problems. An
application of modified equivalent surface boundary
using the hybrid FEM-FDTD technique [1] is
presented and discussed in terms of the memory
locations and processing time required for updating the
equivalent surface currents from FEM to FDTD
methods. A reduced equivalent surface size that
encloses the radiating part of the antenna is studied and
the results are compared with different sizes of the
equivalent surface configurations. Several examples
are presented and the results were stable and quite
reasonable with published data. |
