Abstract

Microstrip patch antennas are well-known for their lightweight, compact, and cost-efficient design, making them perfect for transmitting and receiving electromagnetic signals. They are simple to manufacture, extremely versatile, and can be effortlessly incorporated into a wide range of systems. This research presents a slotted circular microstrip patch antenna (SCMPA) with a defected ground structure (DGS) designed specifically for biosensing applications. Circular patch antennas are especially beneficial due to their capability to generate an omnidirectional radiation pattern within the plane of the patch, removing the necessity for extra components or complex designs to ensure full coverage. Introducing intentional voids or patterns into the ground plane optimizes the antenna’s current distribution, enhancing its radiation characteristics, including increased gain and improved directivity. The proposed SCMPA achieves a gain of 13.71 dBi, categorizing it as a medium-gain antenna that provides broad coverage while maintaining a compact form factor. It finds applications in RFID systems, wireless communication, environmental monitoring, and biosensing technologies, such as wearable health monitors, medical implants, and remote patient monitoring systems. The antenna operates at a resonance frequency of 3.05 GHz, with a return loss of -25.9645 dB at 2.9 GHz, ensuring efficient power transfer and excellent impedance matching, highlighting its suitability for various communication and biosensing applications.
