Abstract

In this paper, we have shown that it was still possible to get a very good diversity system gain for very closely spaced UMTS PIFAs (0.027 lambda₀) positioned on the PCB of a small communicating object by using the neutralization technique. The goal is to see how efficient can be the neutralization technique when the radiators are separated by a very small distance or in other terms, how close can be placed two small UMTS PIFAs on a small ground plane while still having a satisfactory DSG with our neutralization technique. Several measurements will be soon conducted in the Bluetest reverberation chamber of Chalmers Institute to confirm these values.
