Design and Analysis of U-Slot Microstrip Patch Antenna for ISM Band Applications

The design of U-slot microstrip patch antennas is the objective of this paper. This U-slot patch antenna can produce dual band operation. A configuration model was utilized for the purposes of designing, simulating, and analysing a microstrip patch antenna with a U-slot loaded over two dielectric layers. Miniaturization is accomplished with the help of RIS, which stands for reactive impedance surfaces. Simulation parameters are employed in the process of determining antenna framework such as Gain, Polarization, Return Loss, and Impedance. The performance of the suggested U-slot, RIS-based antenna was superior to that of the regular patch antenna and the patch antenna combined with the U-slot. Applications that make use of Bluetooth are a good fit for the proposed antenna. This antenna is mainly used for ISM band for required bandwidth and proper applications. Microstrip patch antenna with reactive impedance surfaces as in results is providing better results than normal patch antenna.
