Teknologi Ultra-wideband atau biasa dikenal UWB merupakan sebuah teknologi wireless yang digunakan untuk mengirim data pada tingkat di atas jarak pendek dengan menggunakan daya yang relatif kecil. Pengaplikasian WBAN menggunakan antena wearable karena memiliki bahan yang fleksibel dan cocok untuk teknologi telemedis serta memiliki banyakkeunggulan seperti ukuran yang kecil, ringan, mampu bekerja pada frekuensi yang cukup lebar,dan pabrikasi yang mudah serta membutuhkan biaya yang terjangkau. Dalam penelitian ini dilakukan perancangan antena wearable monopol planar patch heksagonal dengan frekuensi ultra wide-band rentang 3.1-10.6 GHz dan menggunakan bahan tekstil Cordura Delinova 2000 untuk bagian substrat, coppertape untuk bahan konduktor groundplane dan patch. Ditambahkan metode UC-EBG pada perancangan antena monopol planar pada penelitian ini yang bertujuan untuk meningkatkan parameter antena, meningkatkan gain, dan mengurangi back radiation. Pada penelitiam ini dilakukan analisis performansi pada antena dengan melakukan beberapa perubahan posisi UC-EBG untuk mendapatkan antena dengan spesifikasi paling baik. Setelah dilakukan simulasi dengan perhitungan yang ada, diperoleh hasil parameter antena yang ditinjaudi frekuensi 5GHz dengan Return Loss sebesar -16.55, nilai VSWR sebesar 1.349, nilai gain sebesar 4.754 dBi, dan nilai SAR sebesar 1.277 W/Kg.
Ultra-wideband technology or commonly known as UWB is a wireless technology thatis used to transmit data at rates over short distances using relatively little power. The applicationof WBAN uses a wearable antenna because it has flexible materials and is suitable for telemedicine technology and has many advantages such as small size, lightweight, able to work on a fairly wide frequency, easy manufacturing and requires affordable costs. In this research, the design of a hexagonal planar patch wearable monopole antenna with an ultra wide-band frequency range of 3.1-10.6 GHz was carried out and used Cordura Delinova 2000 textile material for the substrate, copper tape for the groundplane and patch conductors. The UC-EBGmethod is added to the planar monopole antenna design in this study which aims to increase theantenna parameters, increase gain, and reduce back radiation. In this study, performance analysis was carried out on the antenna by making several changes to the position of the UC- EBG to get the antenna with the best specifications. After performing the simulation with the existing calculations, the results of the antenna parameters that are reviewed at the 5GHz frequency are obtained with a Return Loss of -16.55, a VSWR value of 1.349, a gain value of 4.754 dBi, and a SAR value of 1.277 W/Kg.
