In designing a patch antenna, substrate layer is the main element where the basic performance of the patch antenna highly contributed by the substance. For military purposes, an attachable antenna on the gear suit made from Ripstop Nylon is highly demanded in promoting smart wireless communication systems. Therefore, in this paper, we present a preliminary measurement technique to measure the dielectric constant of Ripstop Nylon material using open-ended coaxial probe method. To clarify the accuracy of measurement, proven method has been calibrated with standard material (deionized water). From the results, dielectric constant for Ripstop Nylon in between 1.32 to 1.44, and closely agree with existed data presented by previous papers.","PeriodicalId":171480,"journal":{"name":"2022 IEEE International RF and Microwave Conference (RFM)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126616554","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To make a Koch fractal antenna, a regular rectangular patch is modified with rectangular slots along the bottom edges on the left and right and a narrow triangular cut along the patch's intense top, left, and right sides. The Computer simulation technology (CST) Studio 2017 software simulator, which uses FDM (finite-difference methods) is used to study this structure. For low manufacturing costs, the suggested antenna is incredibly simple to combine with microwave circuitry. To design a triple-band micro strip antenna with frequency bands of 0.72 GHz, 3.89 GHz, and 5.45 GHz, Koch technique is suggested in this study. When the Koch fractal micro-strip antenna is used, the simulation results show that the antenna operates in tri - bands with return losses of -20.1 dB, -26.24 dB, and -11.79 dB at 0.72 GHz, 3.89 GHz, and 5.45 GHz respectively.
