IBM ThinkPad X30 Series
The two Meander (Inverted F type) antennas are built in the left and right top sides of LCD as
shown in the Photo. Those diversity antennas are not used simultaneously. One of the antennas
is selected automatically or manually to have a good quality of radio communication. The
selected antenna performs transmission or receiving in half duplex alternatively.
