Abstract :
Dielectric materials are confronted with
conduction and dielectric loses, this has led to low signal
gain low radiation efficacy. The purpose of this research
work is to improve the signal losses of the existing
antenna on the new to analyse different substrates, that
is the design frequency was kept constant in order to
check the responses of the radiation efficiency and gain
performance of the antenna. This steady adopted the
application of Friis Transmission Technique with the
aim of analysis different substrates with respective gain
properties under investigation. The following substrates
were used including: foam 1.05, RT Duroid 2.2, Fr4 4.4,
Bakelite 4.8 and Taconic 3.2 and after analysing
different substrates using HFSS-High Frequency
Structure Simulator the best based on least amount of
signal losses is foam. The results obtained showed that
foam as a substrate had the least amount of losses. The
results obtained also showed that foam had the best
radiation efficiency and gain. Friis transmission
technique was also employed for determination of the
signal distance. How much the signal travelled. And also
the results showed us that the signal from the foam
substrate travelled the longest distance.
