Abstract:

This paper describes a compensation method of ultra wideband mutual coupling using finite impulse response (FIR)-filters to equalize the frequency characteristic of antenna interactions. The result is a compensated far-field impulse response, which yields an radiated electric field similar to one caused by an ideal uncoupled antenna array. On the basis of an antenna array impulse response, which includes antenna interaction, a mathematical framework is derived to configure the FIR-filters. Finally, simulations are presented, where the preprocessed radiated electric field of an antenna array coincides with the electric field caused by a single isolated antenna without any coupling effects.
