ANALISIS PENGARUH JENIS SUBSTRAT TERHADAP KARAKTERISTIKANTENA MIKROSTRIP PERSEGI PANJANG DENGAN FREKUENSI KERJA 2,4 GHZ
Abstract: This research
motivated by the influence kind of substrate to the dimensions of the antenna,
gain and impedance, to get the design of antenna with the characteristic
consistent with the standards and need of the designer takes the right
material. This research to prove the effect of microstrip substrate. The
substrate according to the design (features) and desirable for a rectangular
microstrip antenna 2,4 GHz. Method used is analisis from the result of the
simulation using CST studio suite, the process follow some steps: (1) study
literature (2) determining the types
antenna (3) determining the specifications of the microstrip antenna
(2,4 GHz frequentz of resonance, return loss <-9,54 dB direction) (5) calculating
the dimention of the antenna based on the theory (4) simulation using CST
studio suite (5) analyzing the result of simulation. From the research can be
concluded that there is a value 𝓔r of the gain the
rectangular microstrip antenna where the larger value 𝓔r
and the gain will be smaller. There is an influence in the value 𝓔r
foward the bandwidth to the square antenna microstrip. Which is the more larger
the value 𝓔r bandwidth make the value smaller. There is an
influence in the value 𝓔r foward beamwidth to the
square antenna mictrostrip, which is the more larger that value of 𝓔r,
beamwidth will be larger. To design the antenna with high value more than 90° 5dB that is use for the value
of 𝓔r
between 1-3. To design the antenna with the beamwidth that value more than 0,03
GHz that use for the material with value of 𝓔r between 1-3.
