Abstract
An improved loop antenna (10) comprises first (12) and second (16) conductive loops. Each of the first and second conductive loops has a discontinuity (14, 18). The first and second conductive loops (12, 16) are arranged substantially concentrically to form a capacitive coupling such that the tuned frequency of the loop antenna (10) has improved protection from external capacitance effects.
