Abstract :
Authors have proposed an L-probe fed stacked rectangular microstrip antenna combined with a ring antenna for triple-band operation in ITS. In this paper, the relationships between geometrical parameters of the antenna and antenna characteristics (VSWR, axial ratio and bandwidth) at three frequency bands are clarified by simulation. Moreover, antenna for GPS/VICS/ETC is designed.
