Abstract

Objective: This study is to design and analyze a rectangular microstrip patch antenna (MPA) for detecting 3,4-Methylenedioxy methamphetamine (MDMA) in the human body. The antenna's performance characteristics including resonant frequency, return loss, gain, VSWR, and radiation pattern are investigated to assess its suitability for drug detection applications. Methods: The rectangular microstrip patch antenna (MPA) is designed using electromagnetic simulation software. The antenna is optimized to resonate at a frequency sensitive to the presence of MDMA. The simulation results are analyzed to determine the resonant frequency, return loss, gain, VSWR, and radiation pattern of the antenna. The antenna's performance is evaluated under various conditions to assess its effectiveness for MDMA detection. Results: The proposed rectangular microstrip patch antenna (MPA) exhibits a resonant frequency of 1.3918 THz with a return loss of 41.136 dB and a VSWR of 1.0177034. The antenna achieves a gain of 7.993 dBi and demonstrates a radiation pattern suitable for MDMA detection. These results indicate that the designed antenna is promising for detecting MDMA in the human body due to its specific resonant characteristics and performance metrics. Conclusion: The designed rectangular microstrip patch antenna (MPA) shows potential for detecting 3,4-Methylenedioxy methamphetamine (MDMA) based on its resonant frequency, return loss, gain, VSWR, and radiation pattern. The antenna's resonant frequency aligns with the presence of MDMA, making it suitable for sensing applications aimed at drug detection in biological environments. Further experimental validation is recommended to verify its performance in real-world scenarios.

Keywords: Microstrip patch antenna, MDMA detection, Resonance frequency, Return loss, VSWR.
