"At 300 MHz, the excited dipole has an approximate 3[lambda]/2 electrical length where the maximum of current is located away from the feeding position, exciting a longitudinal two-peak SAR distribution..,..[The] passive shielding plate exhibits a half-wavelength eigen-resonance, which yields a transversal two-peak SAR distribution." (6) Distributing the peaks in this way creates four low peaks and a much more uniform field than in the 25-cm device.
