By analysis, they found that the key to high efficiency was series resonant operation using small and moderate Q ferrite core inductors, enabling soft-switching and high frequencies. In addition, the high Author: Minh T. Nguyen, Cuong V. Nguyen, Linh H. Truong, Anh M. Le, Toan V. Quyen, Antonino Masaracchia, Kei. A ferrite-core transformer matches the three paralleled feed lines to 50 Ω in the feed box. Adjustment and Measurements Computer modeling shows virtually no coupling between the loops, so each can . Microwave Polarizers, Power Dividers, Phase Shifters, Circulators and Switches covers the full scope of the subject matter and serves as both an educational text and resource for practitioners. Among the . The 1/2-wave meter doublet with ladder line all the way to a bifilar choke/balun in or near the tuner is a much better antenna for , provided you adjust the ladder line length to avoid the voltage and .

The A promising application of ferrites is for "square - loop" . Please recognize that an antenna need not be resonant in order to be an effective radiator. There is in fact nothing magic about having a resonant antenna, provided of course that you can devise some efficient means to feed the antenna.

Abstract. Effects of nuclear irradiation on the magnetic properties of 14 representative core materials were investigated.

Measurements before, during, and after irradiation were made at a flux level of. This is much more pronounced with very high perm, square loop materials than with ferrites. Here are some BH curves from McLyman as example: You can see why this core loss current step is hard to.
