Wideband planar dipole based on dual-layer artificial magnetic conductor
The Journal of Engineering, 2019 A wideband planar dipole based on dual-layer artificial magnetic conductor (AMC) is designed. First, the size of dual-layer AMC is reduced by more than half, and the in-phase band is wider than the single-layer AMC.

A Low-Profile, Triple-Band, and Wideband Antenna Using Dual-Band AMC
Sensors, 2023 When a wideband antenna is backed by an artificial magnetic conductor (AMC) reflector, the bandwidth is reduced. With the optimization of the shape of the AMC it is possible to exhibit multiband behavior, but the problem becomes complex if the bands are ...

Bianisotropic Susceptibility Theory of Artificial Magnetic Conductors
2023 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting (USNC-URSI), 2023 Over the past 30 years, Artificial Magnetic Conductors (AMCs) have generated immense interest in the microwave community. However, their description has been restricted to crude RLC design or subsidiary transmission-line network modelling. This paper introduces an electromagnetic theory of AMCs in terms of bianisotropic susceptibilities.
