Microwave antennas and heterogeneous substrates using nanomaterial fabrication techniques

Microstrip patch antennas with 3-dimensional substrates

“…In a related area, the author of this paper is considering manufacturing antenna systems with heterogeneous substrates using emerging nanotechnology fabrication processes [29][30][31][32][33].…”

Review of artificial dielectrics containing small scale inclusions

“…Furthermore, the electric fields are not uniformly distributed under the antenna and therefore it is advantageous to vary the local permittivity within the substrate and mapping the values to the electric fields -this can be potentially achieved by varying the volume density of small scale inclusions. Locating a high permittivity where the electric fields are small has been shown to increase the bandwidth [32][33][34][35][36]. Patch antenna substrates with small scale inclusions have been considered [22], [37].…”

Antenna performance on quasi synthetic media

“…The scattering parameters of a plane wave excitation incident of the heterogeneous substrate were processed using a Resonant Inverse Scattering Formalism [18]. This methodology was initially verified by analyzing homogeneous substrates [19]. The electromagnetic simulations showed good agreement with the canonical equations.…”
