A virtual ground balun for the
suppression of anyone of the two branches of an ½ wavelength open dipole antenna.
PATENT N. ITAPA20030019
Virtual ground balun with built in S.W.R. meters. It is
designed around our Suppressor circuitry
and has 3 built in S.W.R. meters, one for each of its ports. description
Our all-in-one original
apparatus to carry out measurements and experiments on the open and folded
dipole antennas and on the physics of the hertzian radiation.
A virtual ground balun for
doubling the ½ wavelength folded dipole antenna. PATENT N.
