T The textile material antenna is one of the wearable antennas that can be usedto support health detection in the medical field because the material is flexible andcomfortable to use. One implementation of wearable antennas that can be appliedin medical field is an antenna as an early detection of breast cancer. Nowadays thereare many technologies capable to detect the presence of breast cancer. With thewearable antenna to be designed, it is expected to provide an alternative to earlydetection of health especially early detection of cancer/tumors in the breast.In this research, the design and realization of microstrip antenna with textilematerial in the form of cotton as substrate and Cooper tape as patch. The antennaworks on the Industrial, Scientific and Medical (ISM) Frequency of 2.45 GHz,which is one of the unlicensed bands approved by the Federal CommunicationCommission (FCC) in 1985. One characteristic of antenna that can be used asdetector is to have high gain value. In this study used the Inset-Fed method and theantenna dimension adjustment to be able to obtain the characteristics of the desiredantenna parameters. Thus, the expected antenna that is designed can be used as asupporting tool for early detection of breast cancer. In this research, a microstripantenna was designed with textile material in the form of cotton as the substrate andcooper tape as a patch. The antenna works at an Industrial, Scientific and Medical(ISM) frequency of 2.45 GHz which is one of the unlicensed bands approved by theFederal Communication Commission (FCC) in 1985. One of the characteristics ofan antenna that can be used as a detector is that it has a gain value. tall one. In thisresearch, the Inset-Fed method is used and the antenna dimension adjustment isused to obtain the desired antenna parameter characteristics.From the measurement results, the antenna parameters are able to work wellat a frequency of 2.45 GHz with a VSWR value of 1.023, a return loss of -38.07dB, a gain of 5,975 dBi and a unidirectional radiation pattern.
