VARIOGRAM ANALYSIS OF A DUAL BAND PATCH ANTENNA

In the present study, the variogram analysis of a patch antenna is performed in order to study its performance by examining the return loss that is closely depending on the design parameters. The studied patch antenna is a dual band textile antenna intended for body centric applications. The working frequencies are 900 MHz and 1800 GHz. For the sake of simplicity, only two design parameters are considered. Their effect on the return loss are examined by plotting the variogram and the results are compared with others given by alternative statistical methods such as Monte Carlo and Polynomial Chaos Expansion methods. It is shown that the variogram analysis may be a good technique for parametrical analysis of electromagnetic structures such as antennas
