In fields like astronomy and radar technology,
high-gain antennas are required for long-distance communication. Due to its
relatively large gain, the use of parabolic antennas has become very popular
over time, because they can easily achieve gains of above 30dB at microwave and higher frequencies. Today,
most systems’ success depends on how well the antennas perform. These antennas
are available in different types and sizes. Each antenna’s effective area
usually has less than the actual physical area of the antenna surface. This
means that the unused area of the antenna is massive, and a waste. The aim of
the research is to show that the actual physical aperture of a parabolic
antenna can be reduced as much as possible to equal the effective area, as
given by the antenna formula, thereby saving manufacturing costs, improve the
aesthetics. In other words, the focus of this work is to experimentally show
that reflector antenna can be made of smaller sizes but better performance.
Measurements were taken from different positions from a parabolic antenna, the
signal level measured and compared with signal levels for optimal performance.
