Losses coupled into an electrically small HF loop receiving antenna system from its environment are investigated by analysis and computation using the NEC programme to assess the significance of such effects when superconducting technology is applied. Results are presented showing ground plane and terrain perturbations of the loop performance itself together with the effects of lossy supporting substrates and radiation screens on typical matching capacitors and coils. Q-factors of the order 10… CONTINUE READING
