Performance analysis of FR-4 substrate for high frequency microstrip antennas

This work investigated the use of FR-4 substrate as a possible candidate for antenna design in the X-band. For this purpose single element microstrip antennas have been designed at frequencies ranging from 2 to 10 GHz. The variations in the antenna performance due to frequency increase have been studied. S-parameters have been used as a comparison metric between the simulated and fabricated antennas. The work provided an insight into the performance of antennas. Consequently, the modifications required in the antenna simulation design environment are suggested.
