Mutual Coupling Reduction Using Metamaterial
National Defense Academy Department of Electrical and Electronic
A dipole antenna composed of a composite right/left-handed
(CRLH) transmission line has been proposed. The CRLH
dipole antenna can be miniaturized in the fundamental
resonant mode with n = -1. However, the bandwidth narrows
when CRLH transmission line is used as the antenna element.
In this study, a dipole antenna with a CRLH parasitic
element is investigated. The dipole antenna with the
CRLH parasitic element has band rejection characteristics.
The mutual coupling between two dipole antennas can
be suppressed by arranging CRLH parasitic elements between
the two antennas.
|For experimental verification, the CRLH
parasitic element is composed of the interdigital capacitor
and meander line inductor with 50 microns space. In
addition, large area for milling processing is required
because the CRLH parasitic element is composed of several
The FP-21T Precision allows
us precision that the metamaterial structure with fine
line and space can be fabricated.
