The conductive fabric is developed by using a plain weave technique and the chosen type of yarn is copper covered yarn. For simulation, Texgen textile software is used to generate fabric structure in CST. The results of simulated and fabricated textile antenna are compared. Next, two textile antennas of the same size and dimension are tested to compare the performance using two different substrates which are polyester and FR-4. Both antennas have the same size, in terms of patch and substrate but different in substrate material. At the end of the studies, it is noticeable that Texgen software is a reliable software that can indicate the real structure of fabric for textile antenna and this software is able to work together with CST Microwave software. There is a good agreement between simulation and measurement results as the simulation results closely reassemble the fabricated textile antenna results. From this studies, it is important to determine the dielectric constant of the substrate and also others crucial parameters such as thickness of substrate and the substrate tangent loss. Those parameters are crucial as it will affect the performance of the antenna. Throughout this work, the conductive fabric placed on antenna shows that it can radiate signal and able to be applied on textile antenna.","PeriodicalId":111726,"journal":{"name":"2018 IEEE International RF and Microwave Conference (RFM)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131239856","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}

An FR4 epoxy dielectric substrate frequently applied for the antenna deployment results in high losses due to its inherent characteristics, hence this leads to lower the efficiency. In this paper, an experimental approach to lower the resonant frequency of microstrip circular patch antenna by using artificial dielectric material (ADM) made of a modified styrofoam is proposed. By inserting a number of thin conductor wires into the styrofoam as a host material, the relative permittivity of host material could be increased. The electric fields distribution for TMz resonant mode in the microstrip circular patch antenna becomes a reference for placing the thin conductor wires. The result of experimental approach shows that the ADM made of 110 pieces 0.5mm diameter thin conductor wires inserted into a styrofoam could significantly lower the resonant frequency of conventional microstrip circular patch antenna around 48% from 1832.3MHz to 951.2MHz. In other term, there is an increase of effective relative permittivity up to 270%.","PeriodicalId":111726,"journal":{"name":"2018 IEEE International RF and Microwave Conference (RFM)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125729344","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}

The desirable substrate for wireless body area network (WBAN) application should be flexible, waterproof, stretchable, withstand against harsh environment and reliable under bad weather condition. Textile can be one of the options. However they are easily influenced by the surroundings especially when they operate in harsh environment or under bad weather conditions. Therefore, polymer such as polydimethylsiloxane (PDMS) is proposed as an alternative material which could comply with aforementioned working environment. Using PDMS as substrate, an antenna integrated with high impedance surface (HIS) is designed and studied for WBAN application at 2.4 GHz. The overall dimension of the presented design is 49.5×33×4 mm3. The design demonstrates satisfactory performance in term of gain (6.4dBi) and efficiency (~65%). Furthermore, the design has reduced radiation towards the body by 26 dB. Simulation investigations of the proposed antenna has been performed in the conditions where it is placed very close to human body and the level of the specific absorption rate (SAR) is monitored to ensure users safety. Based on the results, the proposed antenna design can be considered as an ideal candidate for WBAN devices in the future and comply with safety standards.","PeriodicalId":111726,"journal":{"name":"2018 IEEE International RF and Microwave Conference (RFM)","volume":"371 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133243367","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}
