Performance Enhancement Using Circular Cut Shape Rectangular Microstrip Patch Antenna
In this paper, the authors designed a circular cut shape microstrip patch antenna for the performance comparison with the normal microstrip patch antenna using the spectrum analyzer. The return loss of circular cut shape microstrip patch antenna designed at the resonant frequency of 2.42GHz has been compared with the normal microstrip patch antenna at a substrate height of 1.6mm. They get improvement in return loss. This paper shows the faithful return loss means they get dual band operation for the circular cut shape on the patch side and a very good practically value of VSWR (Voltage Standing Wave Ratio) obtain at the 2.42GHz resonant frequency.
