Abstract (in Japanese) (See Japanese page) 
(in English) The Shinkansen antenna for overhead line voltage detection and wireless communication antenna has both the function of detecting the overhead line voltage of 60 Hz and the function of wireless communication in the VHF band. Wind noise is generated by this antenna because it protrudes from the roof of the train, and it is required to reduce noise. In order to reduce noise, it is particularly necessary to shorten the detection rod that detects overhead line voltage. Therefore, we propose a shared antenna configuration that uses a folded monopole structure and a parallel resonant circuit to reduce the length of the detection rod. When the detection rod is shortened, the performance of overhead line voltage detection deteriorates, but the deterioration is minimized by making the antenna substrate area as large as possible within the optimal antenna radome shape that reduces noise. The effectiveness of the proposed antenna is confirmed by simulations and measurements.
