Judul : Planar Array-Antenna with Improved Radiation Characteristic Using Spiral Shaped DGS

Abstrak :
In this paper, the improvement of radiation
characteristic for planar array-antenna by incorporating spiral
shaped defected-ground-structure (DGS) is presented. The
proposed planar array-antenna which is designed to work at the
frequency of 2.4GHz consists of 4×4 elements in which the inset
feed method is employed to excite each antenna element. The
planar array-antenna is implemented using a 1.6 mm thick FR4
epoxy dielectric substrate and analyzed through a simulation.
The simulated result of radiation characteristics for the planar
array-antenna is then validated by experimental characterization.
It shows that the spiral shaped DGS incorporation yields
measured radiation characteristics of the planar array-antenna
to have the bandwidth response of 140 MHz and the gain
achievement of 10.47 dB at its resonant frequency. This is
comparable to the simulated result which is showing the
potentiality of spiral shaped DGS usage in the improvement of
radiation characteristics.
