An analytical approach to modifying the properties of dielectric substrates composed of nanomaterials

By Chinwe C. Njoku, W.G. Whittow and J.C. Vardaxoglou


Presented at the 2010 Loughborough Research Student Conference.The aim of this research is to fabricate antennas and dielectrics\ud out of nanomaterials. This method has the potential of\ud integrating the whole antenna structure into one process. Since\ud nanomaterials are extremely small, larger structures (~mm)\ud can be created by suitably arranging many such particles\ud (metallic and/or non-metallic), and thus resonance at\ud microwave frequencies can be achieved. Fabrication and\ud physical advantages include potentially faster fabrication\ud processes and reduced production costs [1]. Using\ud nanomaterial fabrication methods will enable novel and\ud bespoke substrate properties, by controlling the size and\ud volume ratio of the particles. Electromagnetic advantages\ud (bandwidth, size and efficiency) can be achieved by varying\ud the local permittivity with the local electric field strength, or\ud by creating substrates with equal permittivity and\ud permeability
