Abstract (in Japanese) (See Japanese page) 
(in English) We have already propose a new estimation method for far-field gain of hybrid broadband antenna and log-periodic dipole array antenna at near distance. Our proposed method is based on the techniques of a time domain analysis and a time-frequency analysis using a short time Fourier transform. This method can be determined the antenna distance at each frequency. In this paper, we estimate the antenna gain of biconical antenna using our proposed method. The difference between far-field gain and the estimated near-field gain using our proposed method is less than 0.05 dB at 10 m antenna distance and less than 0.3 dB at 3m antenna distance in the frequency range from 30 MHz to 200 MHz.
