Inverted-F Antenna for Mobile Communication Part-II

The inverted F-antennas are the popular and extensively used in mobile handsets. Due to compactness, small size and conformal nature these can be easily mounted anywhere in the handsets. The hybrid finite element method (FEM) in conjunction with finite difference time domain (FDTD) using modified equivalent conducting surface boundary is implemented to investigate the characteristics of IFA at 1800 MHz frequency. FEMLAB and FORTRAN 90 are used to model the antenna along with scatterer with low reflecting material for the purpose to truncate the fields above the ground plane and antenna. The simulation results found sufficient good to predict the antenna performance are presented. The design confirmed the implementation of the hybrid FEM-FDTD numerical technique
