Abstract: In this paper, the performance of U-slot Rectangular Microstrip Patch Antennas (RMSA) is analyzed by using different flexible substrates. The RMSA is designed to operate for a resonant frequency of 2.45 GHz with flexible substrate materials like Polydimethylsiloxane (PDMS), GML-1032 and Polyethylene. The antenna parameters like reflection coefficient, voltage standing wave ratio (VSWR), radiation pattern, bandwidth and cost are analyzed by keeping all the substrate height same and the value is 2.5mm. U-slot cutting is used in the patch to overcome the narrow bandwidth limitation in RMSA because U-slot tunes the higher order orthogonal mode resonance frequency of the patch with respect to fundamental mode to realize the wider bandwidth. The maximum bandwidth of 80MHz is achieved with the use of PDMS. The antenna is simulated using HFSS software.
