This disclosure provides systems, methods and apparatus for wireless power transfer and particularly wireless power transfer to remote systems such as electric vehicles. In one aspect the disclosure provides for an apparatus for wirelessly transmitting power. The apparatus includes a first conductive structure configured to generate a first magnetic field in response to receiving a first time-varying signal from a power source. The apparatus includes a second conductive structure configured to generate a second magnetic field in response to receiving a second time-varying signal from the power source. The first and second structures are positioned to maintain a substantial absence of mutual coupling between the first and second magnetic fields.
