Presented is radio frequency antenna circuit for portable and/or compact electronic devices. Embodiments comprise an antenna (11, 12) connected to an unbalanced current feeding arrangement (15). An inductance (13, 14) may be connected between antenna elements (11, 12) and arranged to compensate for the capacitance formed by the two antenna elements. The unbalanced feeding arrangement may generate common mode currents which increase the overall radiation resistance and efficiency of the antenna circuit. |
