Microstrip Patch Antenna: A Design to Study the Parametric Trade-off

Abstract

In the proposed work an experimental design of microstrip patch antenna has been developed to study the various parameters controlling the performance of the antenna. A microstrip patch antenna for optimum return loss, gain, directivity, efficiency and radiated power has been developed. Various design for rectangular microstrip patch antenna, 1x1, 1x2, 2x2, 1x4, 2x4 and 4x4 rectangular microstrip patch arrays with inset feed microstriptechniques have been implemented. After the implementations, major performance governing parameters are plotted against frequency to analyze the characteristics of the developed rectangular microstrip patch antenna. Due to stentorian return losses and complex feeding techniques for higher order arrays, the array design has been limited to 4x4. The frequency of designed antenna has been selected as 2.4GHz. All the designs and have been simulated in Advanced System Design (ADS). Metric graphs of reflection losses, gain, directivity, efficiency and radiated power have been plotted against the frequency using the same. Though plotting of the radiation pattern lobes is possible, it has not been implemented due to its less accurate degree of measurement. Finally, all the plotted metrics have been studied, and a trade-off among the parameters has been analyzed for the optimum performance of the designed rectangular microstrip patch antenna. This trade-off analysis can be used to implement application-specific rectangular microstrip patch antennas for optimum performance in their respective field.
