Abstract
A flexible coil with improved tolerance for overlapping antennas and with reduced susceptibility to the introduction of image artifacts as a result of overlapping antennas utilizes antennas with multiple conductors extending in parallel for the length of the antenna. Each conductor is connected to the other conductor at each end creating parallel conduction paths for the length of the antenna. The parallel conduction paths reduce the resistance of the antenna which, in turn, improves the quality factor of the antenna. The improved quality factor results in antennas that are less susceptible to image artifacts being induced in the antenna due to coupling from an overlapping antenna.
