Abstract
A switched meander line structure is substituted for a lumped element antenna tuner for an order of magnitude increase in gain due to the use of the switched meander line architecture. The use of the meander line with relatively wide and thick folded legs markedly decreases IR losses over wire inductors whose wire diameters at one-tenth of an inch contribute significantly to IR losses. Additionally, placing solid state switches to short out various sections of a multi-leg meander line at high impedance nodes reduces IR losses across the switching elements in the tuner.
