Abstract
A method of operating a higher conductivity broadband loaded meander line antenna (10) is provided wherein the meander line is positioned on a sheet of a lower conductivity material (22) having a conductivity of from about 0.01 siemens/m to about 0.10 siemens/m; and allowing a first electrical current to flow in a first current path in the meander line. An electrical field is formed in the vicinity of the lower conductivity material and a second current flows in a second current path in the lower conductivity material, whereby anti-resonance in the meander line loaded antenna is diminished so that a broadband response can be achieved over bandwidths of 5:1 or more. An assembly for carrying out this method is also disclosed.
