SUMMARYIn this paper, we propose and discuss efficient GPU implementation techniques of absorbing boundary conditions (ABCs) for a 3D finite-difference time-domain (FDTD) electromagnetic field simulation for antenna design. In view of architectural nature of GPUs, the idea of a periodic boundary condition is introduced to implementation of perfect matched layers (PMLs) as well as a transformation technique of PML equations for partial boundaries. We also present efficient implementation method of a non-uniform grid. The evaluation results with a typical simulation model reveal that our proposed technique almost double the simulation performance and eventually achieve the 55.8% of the peak memory bandwidth of a target GPU.

In the VICS band, the antenna can receive signals with uniform level within the communication area [3,4].

Abstract-A stacked rectangular microstrip antenna with a shorting plate combined with a rectangular ring microstrip antenna is proposed for triple band operation (GPS, VICS and ETC) in ITS. The two microstrip antennas are excited by an L-probe feed. In the ETC band, axial ratio deteriorates due to asymmetrical distributions of the electric current in the ring microstrip antenna. In this paper, an approach to improve the axial ratio for ETC is also proposed. The proposed antenna has the proper radiation patterns and impedance matching for the GPS, VICS and ETC.

A stacked patch microstrip antenna combined with a stacked ring microstrip antenna is proposed for quadruple band operation. The two antennas (a stacked patch microstrip antenna and a stacked ring microstrip antenna) are excited by an L‐probe feed. The impedance bandwidth is enhanced by using double resonance at all frequency bands. With simulations, the relationships between the antenna's geometrical parameters and operational frequencies are clarified. The operational principle for quadruple band is explained by the simulated electric currents. The antenna is designed for Wi‐Fi (2.45/5.25/5.6 GHz bands) and mobile WiMAX (3.5 GHz band).
