Designing microwave patch antennas using heterogeneous substrates
conference contribution
posted on 2012-07-12, 11:10 authored by Chinwe Njoku, William WhittowWilliam Whittow, J. C. VardaxoglouThis paper introduces the concept of designing
microwave patch antennas by creating synthetic heterogeneous
substrates with small scale inclusions. These inclusions embedded
in a host dielectric can be used to control the dielectric properties
and create bespoke effective permittivity values. Heterogeneous
patch antennas at 2.4GHz are simulated in this paper. By
deliberately mapping the permittivity values to the electric fields,
the antenna behavior can be controlled and a dual band
frequency was introduced. The local regions with micro-scale
inclusions showed good agreement with a homogeneous substrate
section with the same predicted permittivity. These
heterogeneous substrates can be potentially created using
nanomaterials.
