It is shown that the MB antenna, which uses the handset PCB as the radiating element, is equivalent to a full-wave dipole, i.e. each arm is half-wavelength long. This enhanced length of the dipole, and hence its improved properties, is achieved due to the fact that in the MB antenna the radiating arms are short-circuited at their ends. This approach allows increasing the antenna's gain by 3dB, as compared to the conventional dipole, while removing the need for a separate antenna to be installed on the PCB.
