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.

In this study, we developed an analytical model of slot-loaded rectangular microstrip patch antennas based on the simulation results by varying slot parameters. The dominant resonant frequency predicted by such a model is in strong agreement with the experimental results measured at several locations of slot-loaded rectangular microstrip patch antennas. The model enables a reliable and quick computation of the resonant frequency, which generally follows a harmonic behavior that nearly resembles the resonant frequency of a microstrip antenna without a slot, which can be related to a small change in the impedance caused by the slot position. Results showed a good agreement between simulations and measurements for all the slot positions. Mathematical analytic functions to describe the changes in specific characteristic parameters of the slot-loaded rectangular microstrip patch antennas are also included.
