In order to minimize this wasted energy and
traffic collisions, is to use another type of antenna called “smart antenna”.
These antennas can use select able radiation patterns depending on the
situation and thus drastically minimize the unnecessary energy waste. Smart
antennas also provide the ability to sense the direction of incoming signals
which is favorable for physical layout mapping such as orientation.
This project shows the prototyping of a new type
of smart antenna called the SPIDA smart antenna. This antenna is used to
produce smart antenna designed for the 2.4 GHz frequency band. The SPIDA smart
antenna can use sixty-four different signal patterns with the control of six
separate directional modes, amongst these patterns are six single direction
patterns, an omnidirectional signal pattern and fifty-six combi-direction
patterns. The study presents complete building instructions, evaluation data
and functional drivers for the SPIDA smart antenna.
