Paper Abstract

In this paper, a method to calculate the VLF transmitting antenna's bandwidth and frequency characteristic is proposed by comparison of normalized signal power spectrum at antenna feed point with that at far field point, since a VLF transmitting antenna behaves as a filter to the signal at its feed point. Power spectrum data from four VLF transmitting antennas (operation frequencies are 21.4k, 19.8k, 22.2k and 24.8k respectively) are available, and respective bandwidths are calculated by the new method. Results show the validity of the method. This method need no details of the antenna's parameters. It is a new and simple way to find out VLF antenna's bandwidth and its MSK efficiency.
