Antenna, Flexible Material, Wearable Technology


The design and study of a flexible monopole antenna are presented in this work. The proposed antenna design operates in the Industrial Scientific Medical (ISM) band at frequencies between 2.4 and 2.5 GHz, which makes it appropriate for wearable technology. The proposed antenna can be used with wireless technologies including 2.4 GHz RFID and Wi-Fi. An antenna is made from a flexible material. The radiating patch is a conductive fabric with a conductivity of 1250 S/m. The felt is used as the substrate with a dielectric constant of 1.38. The antenna is designed and analyzed by CST Microwave Studio with and without a human body. The antenna simulates and measures at the chest and arm to consider the effect of a human body on the designed antenna. The radiation pattern, the |S11| and gain are measured to verify the antenna performances. The results illustrate that the proposed antenna is appropriated for wearable technology using for frequency between 2.4 GHz and 2.5 GHz.
