Abstract (en)
Coaxial wave resistance transformer for dividing up high frequency power uses (/4 leads (L1 to L4) which are arranged between the first connection (K1) and the second connections (K2 to K4) concentrically surrounding one another at least in part. The leads can be arranged so that each open end of one lead forms the start of the following lead. The leads can be arranged concentric such that the electromagnet wave increases inversely from lead to lead. At least one lead can be folded so that part of its length surrounds the remaining part of its length.
