In this paper, the authors discuss the performance of various dielectric substrates, having dielectric constants ranging from 2 to 5. These designs are basically rectangular micro strip patch antennas for wireless communication resonating at 2.4GHz. They are simulated using the evaluator's version of the software IE3D and their performances are compared with respect to 'Return loss v/s frequency' and 'VSWR v/s frequency' parameters. The comparison is made for four dielectric substrates: FR4, RO-3003, PTFE (Teflon) and Polyguide. Analysis of each is done and compiled using Matlab to show relative performance.
