A Planar Multislot Antenna with Backplane for Search and Rescue Applications

Abstract

This study focuses on the development of a low-profile planar multislot antenna with backplane that was built specifically for the requirements of search and rescue operations. The antenna presented here serve as the primary focus of this investigation. The planar multislot antenna with backplane antenna that are being considered are planned to be constructed on a substrate that is made of polydimethylsiloxane (PDMS). PDMS is selected because of its desired features, which include its durability, flexibility, resistance to water, and adaptability for deployment in demanding environmental circumstances. The usage of the search and rescue application necessitates the operation at a relatively lower frequency of 406 MHz, which in turn necessitates the utilization of antennas that have a longer electrical length. As a consequence of this, these antennas have a propensity to have larger physical dimensions. In order to circumvent the problem, it is possible to make use of RT/duroid® 6010.2LM laminates substrate, which will result in a smaller dimension due to increase in the relative permittivity constant. This was proved by the results of the simulation, which showed that the antenna functioned at a central frequency of 406 MHz, displaying bandwidth of 228.8 MHz. Concerning the antenna, the bandwidth is equivalent to a fractional bandwidth percentage of 58.28%, when evaluated at -10 dB of the reflection coefficient.
