Abstract
The decoupling of two very closely located resonant dipoles by a similar dipole located in the middle between them has been recently demonstrated. An approximate analytical model of this decoupling was built, validated by exact numerical simulations and confirmed experimentally. In this work we show that the similar decoupling can be achieved using another scatterer, namely a split-loop resonator may nicely replace the dipole. This replacement allows us to broaden the operation band of the antenna system nearly twice.
Highlights
A complete passive decoupling of two resonant dipole antennas 1 and 2 separated by an arbitrary gap d was suggested and studied theoretically and experimentally in [1]

Summary
A complete passive decoupling of two resonant dipole antennas 1 and 2 separated by an arbitrary gap d (the minimal value of d is restricted only by the requirement d r0, where r0 is the wire cross section radius) was suggested and studied theoretically and experimentally in [1].
