The design and characterization of G-patch dualband
printed monopole antenna for GPS and WLAN application has
been investigated numerically and experimentally. The antenna
that has been designed to work at around resonant frequency of
1.6GHz and of 2.4GHz has been realized using an FR4-Epoxy
dielectric substrate with the dimension of 50mm x 50mm and
the thickness of 1.6mm. From the characterization results, it
has been demonstrated that the proposed antenna has been able
to show dual frequency band capability required for the
application. Although there were some slight different
achievement between the numerical and experimental
characterization in term of resonant frequencies, working
bandwidth, and overall gain due to the difference value of
material properties used in the design and realization, i.e.
relative permittivity and loss of dielectric substrate, however,
in general the realized antenna has shown good agreements
qualitatively with the design results.
