4.5 Design Recommendations

Recommendations for Designing the Module Antennas
The design recommendations are as follows:
Issue 01 (2010-12-09)
It is recommended that the module antennas are designed at the upper edge,
left edge, or right edge of the laptop screen. Designing the antenna at the upper
edge is better.
Take the isolation and envelope correlation between the master antenna and
the slave antenna into account when designing the antennas. Keep the slave
antenna away from the master antenna as far as possible. Install the slave
antenna perpendicularly to the master slave. See Figure 4-2, Install the master
and slave antennas in positions 1 and 3 or 2 and 4 but not in positions 1 and 2 or
3 and 4.
