| Abstract: | An analytical formula of the current distribution for the VLF low-construct horizontal antennas(LCHA)is proposed.The equivalent radiation efficiency for the arbitrary LCHA is presented.The effect of the antenna length,feed position,and end condition and earth conductivity on the efficiency is analyzed respectively.Then the efficiency of the LCHA array is formulated and the performance of the parallel array and the fan-shaped array are analyzed and compared. |
