It is clearly seen that the slope of the reactance function may be negative in a lossy situation ... WebThe validity of the Foster reactance theorem for the general lossless or lossy antenna is considered for the straight-wire monopole and half-loop antennas. The finite diameter, lossy or lossless monopole, and half-loop behave as either a series RLC circuit near resonance or a parallel RLC circuit near antiresonance. For the Foster reactance theorem to be valid …
WebApr 10, 2024 · Foster's reactance theorem is an important theorem in the fields of electrical network analysis and synthesis.
