A microstrip patch antenna with Rectangular Complementary Split Ring Resonator (R-CSRR) for sensing applications is proposed in this paper. In recent years, due to the rapid growth of wireless communication systems and emerging technologies, there has been an increased need for microwave antenna designs that are both compact and efficient. This paper introduces an approach to enhance the performance of microstrip patch antennas through the integration of a RCSRR structure. The proposed design provides an operating frequency of 2.58 GHz and s-parameter magnitude of -21.35 dB. The design can act as a high sensitive microwave sensor to detect the dielectric constants of different analytes. Moreover, a range of machine learning regression algorithms have been utilized to accurately forecast the dielectric constant of the analyte by analyzing the frequency response of the sensor. The performance analysis reveals that polynomial regression exceeds other methods, demonstrating a minimal root mean squared error of 0.2948. These machine learning-driven techniques greatly improve the sensor's performance, making it a valuable asset for the future applications in biochemical sensing.
