Abstract :
It is shown that in measurements of mobile handset antennas a cap on the coaxial feed cable inserted relatively close to the handset acts practically like an open termination to the induced currents on the surface of the phone chassis. Therefore, the measurement results with the cap are much closer to those of an isolated handset than without any countermeasures or with ferrite chokes
