With the recent rapid progress in handsets, the downsizing of their antennas is acquiring great importance. Generally, these antennas have been downsized by changing a configuration of the antennas or utilizing materials such as dielectric materials and magnetic materials. Until now, we have investigated a downsizing technique of antennas for handsets by utilizing magnetic materials. The topology...
In this study, we apply uniquely the topology optimization method to optimize the configuration and arrangement of the magnetic materials, which is inserted in the planar inverted F-antenna (PIFA) by using adjoint variable method (AVM) and the FDTD method. The aim of study is to confirm the validity of using topology optimization method for designing the configuration and arrangement of the magnetic...
