MIMO LTE antenna
Mobile communication devices are becoming commonplace in modern societies. The multitude of services offered by such devices typically operate across multiple frequency bands and require antennas that work in all those bands. Add to this requirement restrictions on placement and size of such antennas inside devices and engineers are left with a complex design and optimization problem.
FEKO's Method of Moments (MoM) and its extensions to solve dielectrics are well suited to the design and optimization of mobile antennas. Planar Green's functions, the Surface Equivalence Principle (SEP) and Volume Equivalence Principle (VEP) extensions to the MoM are all available in FEKO, providing designers with simulation methods to solve a wide range of different mobile antenna topologies.
The Finite Element Method (FEM) has also been fully hybridised with the MoM in FEKO, providing users with the ability to blend the strengths of these simulation methods to solve complex dielectric antennas. The FEM-MoM hybrid also provides users with the ability to estimate Specific Absorption Rates (SAR) for new devices in close proximity to humans. Localized peak SAR (1g and 10g cubes) or whole body average SAR levels can easily be computed with FEKO. In situations where the entire body or other electrically large objects have to be included in simulations of mobile antennas, the Multilevel Fast Multipole Method (MLFMM) may be used to accelerate the solutions methods that have already been mentioned here.
