Judul : SR-Based Printed Antenna Array with Reduced Size

Abstrak :
Array of antenna with reduced size is required
for wireless and mobile communications due to the portability
properties. This paper presents a printed antenna array based on
spiral resonator (SR) with reduced size. The proposed antenna
array is configured by use of 2×2 patches of SR structure on two
layers of FR4 epoxy dielectric substrate with each thickness of
1.6 mm. The characterization result of proposed printed antenna
array provides the reflection coefficient (S11) value of –23 dB at
the frequency of 2.4 GHz with the working bandwidth of 95
MHz for the S11 value less than –10 dB. Meanwhile, the gain
of proposed printed antenna array achieves around 7 dB. The
simulation result is verified with the measurement one which
shows a good agreement. Moreover, the size of proposed SR-based
2×2 printed antenna array is reduced up to 27% compared to
the one of 2×2 printed square patches antenna array.
Index Terms—antenna array, size reduction, spiral resonator
