| Abstract(in English) | In this paper, we propose the method to change the frequency band of the Coaxial-Fed circular dipole array antenna in a borehole. We designed and made the two kinds of the circular dipole array antenna for the operating frequencies between 50 MHz and 200 MHz. In order to evaluate estimation of direction of arrival, we introduce time-frequency distribution. |
