Abstract
This paper represents a metamaterial (MTM)
integrated antenna for multi-band operation. MTMs are
integrated on the top and bottom sides of a slot-ring antenna.
The basic slot-ring antenna operates at 2.4 GHz. A single
complementary split ring resonator (CSRR) is placed on the
ground plane and a circular shaped split ring resonator (SRR)
is integrated on the top of the substrate. Integration of CSRR
gives rise to a new resonant frequency at 1.5 GHz. After using
SRR, a third band generates at 3.1 GHz. By using this structure,
a single antenna can cover three operating bands. A microstrip
line is used to feed the antenna. The triple band antenna is
compact because MTM unit cells size is smaller than their
wavelength used to produce resonance at a lower frequency. To
analyze the performance of the proposed antenna reflection
coefficient, radiation pattern, and gain are analyzed. The
simulated gains are 0.71 dBi, 2.9 dBi, and 3.2 dBi corresponding
to bands of 1.5 GHz, 2.4 GHz, and 3.1 GHz, respectively. The
impedance bandwidths are 1.33%, 9.17%, 5.5% at the
1.5/2.4/3.1 GHz, respectively. Good separation between co- and
cross-polarizations is achieved. The three operating bands at
1.5/2.4/3.1 GHz support the allotted bands for GPS, WLAN and
RADAR applications.
