- The carrier frequency of wireless communication keeps increasing to fasten the data rate of communication. Especially, 5G communication now uses millimeter wave of 28 GHz, at which the path loss of the propagating wave is much more severe than at low-GHz range. To compensate for the path loss and enable the long-range communication, it is required to design antenna to have high gain toward desired direction. Currently, we are developing an antenna for 5G communication for railway applications. We consider and optimize not only the electrical property of the antenna, but also the mechanical characteristics to minimize the air resistivity of the antenna structure. Such a multi-physical simulation makes this project particularly interesting and challenging.
