This work has analysed the potential enhancements concerning the angular stabilization and the size reduction of a hexagonal loop-based artificial magnetic conductor (AMC), through a novel approach entailing the use of lumped inductances. As a reward from the lumped inductances' introduction, unit-cell size reduction is achieved while preserving the angular stability and AMC operating bandwidth. A simple design methodology and insight to calculate the optimum lumped inductor value is presented. This work has been focused on UHF-band AMCs due to the size reduction and suitable bandwidth challenges. However the methodology can be also applied not only for lower frequency bands, but also to higher ones, provided that the resulting unit-cell size makes sense in terms of the manufacturing constraints and the lumped inductor's size vs. the metallization one.
