Transposed excitation is essential for the broadband characteristics of LP antenna.


This fact was clearly verified by the results of the calculations conducted
by Prof. H. Nakano (Ref. 1.).

(a) Transposed excitation
for LP antenna.
(b) Non-Transposed excitation
for LP antenna.
A comparison of the input resistances.
