“…All three antennas are suitable for usage in biomedical applications. Figure 1 (a) illustrates the arrangement of antennas for detecting cancer tumor [11], whereas Figure 1 (b) demonstrates how an array of antennas may not only detect the tumor but also determine its precise location [12]. In this paper microstrip patch antennas with three different materials (gold, silver and graphene) are analysed and compared in the terahertz range.…”

The paper explores the design and analysis of a wideband microstrip patch antenna with a metallic patch and a 3x3 split ring resonator (SRR) array operating in the 0.1-5 THz frequency range. The antenna's structure incorporates different conductive materials such as gold, silver, and graphene as a metallic patch. The dimensions of the metallic patch and SRR are calculated to achieve wideband operation within the desired THz range. The SRR array enhances electromagnetic resonance, thereby improving bandwidth and radiation characteristics for medical imaging. The study discusses the equivalent circuit and design equations for the microstrip patch antenna and SRR unit cell. For designing and analysing the proposed antenna, CST Microwave Studio 2019 software have been used. Performance parameters such as return loss, bandwidth, gain, efficiency, directivity, VSWR, and radiation pattern have been evaluated. The advantages and limitations of each conductive material are evaluated to determine their suitability for THz-based medical imaging applications. The goal is to maximize the antenna's bandwidth, gain, and image resolution for medical imaging purposes. The findings highlight the performance characteristics of gold, silver, and graphene as conductive materials for medical imaging applications, facilitating the development of high-resolution, non-invasive imaging systems with improved diagnostic capabilities.
