Abstract
A standard slow wave meander line having sections of alternating impedance relative to a conductor plate is provided with a top shield connected to the conductor plane for the purpose of lowering the resonant frequency of narrow band antennas and lowering the low frequency cutoff limit of wide band antennas due to a higher delay per unit length occasioned by the use of the top shield.
