Polarisasi Melingkar Antena Mikrostrip E Shape Dengan Pencatu Electromagnetic Coupling
Abstract: This paper proposed
a new design of circular polarization E shaped patch microstrip antenna fed by
proximity coupling for Wireless Fidelity applications at operating frequency of
2.4 GHz. To generate circular polarization in the proposed antenna, the next
steps is making three slits on the patch antenna and with this embedded three
slits produces antenna E shaped. Besides that, the proximity coupling fed line
is used to increase the bandwidth of the proposed antenna. In this research the
patch E shaped was put on the first substrate layer while the proximity coupling
feeder was put on the second substrate layer. The substrate material used in
this research is one of the two layers FR 4 Epoxy with relative dielectric
constant ( r) of 4.4 and thickness (h) of 1.6 mm. The circular
polarization can be achieved by adjusting the width and length of the E shaped
antenna. The simulation of this research gave some important antenna parameters
such as axial ratio value of 2.58 dB, return loss of -19.98 dB, VSWR of 1.223
and bandwidth of 151.3 MHz. Finally, its measurement results gave also some
related comparative data such as return loss of -22.12 dB, VSWR of 1.16,
bandwidth of 153.2 MHz, and Half Power Beamwidth of 580.
