The emergence of fan-out packaging for 5G and IoT applications has brought escalating performance concerns that arise from the proximity of radiating components such as antennas to lossy materials such as metals and silicon. These concerns also arise in wearable ('smart skin') electronics where the human tissues act as the lossy substrate. Artificial magnetic conductors (AMC) are widely explored for enhancing the performance of antennas that are in close proximity to metallic surfaces and other lossy substrates such as silicon and human tissue. High-permittivity or high-permeability materials can be used to significantly reduce the sizes of AMCs. Nanostructured materials provide unique opportunities to provide stable properties up to the GHz and mm-Wave frequency ranges. In this paper, novel miniaturized nanostructured AMCs utilizing Barium Strontium Titanate (BST) thinfilms and ceramic-polymer composites are demonstrated through full-wave modeling analysis. The size reduction rates are 50.6 % when using 3 μm of BST thinfilm and 77 % when using 400 μm of ceramic-polymer composites. This concept can be further extended with high-permeability magnetic films, and thicker nanocomposite films to achieve further size and performance improvement for a variety of frequency bands and applications.
