LOOP ANTENNA AND DESIGN METHOD FOR LOOP ANTENNA

摘要

Even when at least one of a capacitor (C₁) connected to a main loop (1) and a capacitor (C₂) connected to an amplification loop (2) cannot be set to an optimal value, a current value of a current (I₂) flowing on the amplification loop can be made sufficiently large by setting the capacitors (C₁, C₂) based on any of an optimal C2 curved line, an optimal C1 curved line, and an optimal C1 straight line that pass through an optimal point (C₁^opt, C₂^opt) of the capacitors (C₁, C₂) and extend along a ridge of contour lines each joining the points where the magnitude of the current (I₂) is equal on a diagram showing a relation of values of the capacitors (C₁, C₂) with the magnitude of the current (I₂).
