Abstract:
This paper investigates the capability of wireless
power transmission (WPT) in a concrete medium using
Cylindrical Dielectric Resonator Antennas (CDRAs). Two dualband
(2.4 GHz and 5.7 GHz) CDRAs were modelled; one CDRA
was embedded in concrete and another CDRA was placed
externally outside the concrete medium. The recorded magnitude
of transmission coefficient from the external to the embedded
CDRA is of relatively high value and demonstrates the capability
of the CDRAs to be used for WPT in concrete. Furthermore, a
sensitivity analysis on the effect of variations of the relative
dielectric constant and loss tangent tan δ of concrete on the
magnitude of the reflection coefficient, S22, and frequency of the
embedded CDRA was performed. This analysis showed that a
reliable WPT could be achieved with cylindrical dielectric
resonator antennas at 2.4 GHz and 5.7 GHz.
