Abstract
This paper investigates the influence of the position of the antennas in a dual-radio mesh router by characterizing
the router components from an electromagnetic point of view. Since the behavior of a wireless
router equipped with multiple devices and antennas can be affected by mutual coupling among several
close conducting bodies, numerical and experimental tests are carried out to provide some suggestions
for an accurate positioning of the antennas. A reference configuration is implemented in an electromagnetic
Computer-Aided Design (CAD) simulator. The most significant numerical results are validated by
performing a campaign of measurements in anechoic chamber and deploying a testbed for the derivation
of the experimental values of throughput, return loss, power density, and directivity.
