Hello buddy...
In the early days of mobile communication, the monopole antenna was used, which was incorrectly assumed to function as a half-wave dipole and its image with the case as the ground plane. In 1968, a precise analysis was carried out, which provided the design concept for the antennas in Mobile Terminal (MT) equipment of Japanese PDC systems.
In the 1980s, planar antenna were developed and recent handheld devices typically contain planar inverted F antennas (PIFA). Today's 3G enabled mobiles not only use a modified PIFA, but also a planar meander line, folded loop, modified dipole, etc.
