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.
