A Flexible Sierpinski Bow-tie Antenna for Search and Rescue Applications

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.
