The purpose
of this research is to investigate the development of a low-profile flexible
Sierpinski bow-tie antenna with fractal iterations. This antenna was
constructed with the specific intention of meeting the requirements of search
and rescue operations. During this
examination, the antenna that is being shown here will act as the primary
focus. The construction of a Flexible
Sierpinski Bow-tie antenna, which is now under consideration, is going to take
place on a substrate that is built of polydimethylsiloxane (PDMS) and has a
relative permittivity of 2.7. Because of
its desirable characteristics, such as its durability, flexibility, resistance
to water, and adaptability for deployment in difficult environmental
situations, PDMS was chosen as the system to be used. In order to make use of the search and rescue
application, it is necessary to operate at a frequency of 406 MHz, which is a
significantly lower frequency. This, in turn, requires the employment of
antennas that have a longer electrical length.
As a direct result of this, these antennas have a tendency to have
bigger dimensions in terms of their physical dimensions. This assertion was validated by the findings
of the simulation, which demonstrated that the antenna operated at a core
frequency of 406 MHz and displayed a bandwidth of 65.53 MHz over its frequency
range. As far as the antenna is
concerned, the bandwidth is comparable to a fractional bandwidth percentage of
15.90% when the reflection coefficient is measured at a level of -10 dB.
