ANALISIS PENGARUH SPACING ANTAR ELEMEN TERHADAP GAIN PADA ANTENA YAGI 5 ELEMEN FREKUENSI 2,4 GHz
Abstract: This research was
motivated by a relatively small laptop power receives Wi-Fi signals, so it
needs a directional antenna that has a high gain Yagi antenna like. This
research is to: demonstrate the effect of spacing between elements to Yagi
antenna gain, get the fixed spacing, knowing gain of Yagi antenna being tested
and how much spacing between elements effect to gain enhancement statistically.
This research use Gain Comparison Method. It is performed by CST Studio Suite
simulation and measurements on 3 measurement points (TP), in a free barrier
room, prevented plywood, and walled. Minimum and maximum of Spacing is 0,05λ
and 0,35λ. The analysis showed: (1) Changes the spacing between elements of Yagi
antenna using CST Studio Suite and the design of the AUT antenna proven effect
on the gain. Changing the minimum space to maximum increase the gain untill the
optimal space, then decreased. (2) The fixed spacing settings by optimal space.
Space-1 optimal of simulation is 0,115λ; 0,205λ for space-2; 0,2λ for space-3,
and 0,22λ for space-4. Space-1 optimal of Yagi AUT is 0,127λ, space-2 = 0,201λ, space-3 =
0,196λ, and space-4 = 0,22λ. (3) Simulastion result has gain 9,8 dB, Yagi AUT
has 9,68 dB, and the commercial Yagi antenna by 14 elements has 11,84 dB. (4)
The regression coefficient for space-1 (X1) is
-58,534 <distance coefficient of signal source to TP (X2). Space-2
(X1) coefficients = -12,53 < X2 coefficient = -12,543. Space-3 (X1)
coefficients = 0,72 > X2 coefficient = -1,289. Space-4 (X1) coefficients =
30,939 > X2 coefficient = -1,332.
