Abstract:

With the fast development of wireless
communication technologies, more compact and
multi-frequency antennas with a low profile, low cost
and superior performances are required. At present,
the simplest and widely used technique to enhance
dual-band and multi-band characteristics in antennas
is by using metamaterials. In this paper, a rectangular
microstrip patch antenna is designed that resonates at
3.5 GHz frequency. To achieve dual band
characteristics in antenna, S-shaped metamaterial
structure is implemented on its ground plane. The
design and simulation of an optimized S-shaped
metamaterial structure for 2.4 GHz frequency is also
presented. In this antenna structure, no modification
in radiating patch is required. Hence, the proposed
antenna has overall dimensions 36x43 mm 2 and
compatible with wireless devices. Ansoft HFSS
simulation software is used to obtain results of
radiation parameters such as return loss, VSWR,
gain, radiation pattern has satisfactory value within
range. For designing of proposed antenna FR4
substrate is used. The experimental and simulated
results are reported which shows a good agreement
between the results.
