This paper presents a compact textile antenna with circular polarization for Industrial, Scientific, and Medical applications, utilizing metamaterial-inspired radiating elements to achieve significant size reduction and enhanced antenna bandwidth. The antenna demonstrates a measured bandwidth of 5.8% and an axial ratio bandwidth of 80 MHz, with perfect matching observed between measured and simulated results.
A compact textile antenna with circular polarization (CP) is implemented for Industrial, Scientific, and Medical applications for wireless body area network with radio band 2.4 GHz. A metamaterial-inspired radiating element is used to achieve a size reduction of up to 85% against the conventional textile antenna. The CP is obtained by trimming the corners of the radiating element. A rectangular slot place with strip line construct a metamaterial-inspired radiator and U-slot is imparted below the radiator by using defected ground structure technique to enhance the antenna bandwidth. This antenna has a physical area of 0.25 x 0.22 x 0.016 lambda g and is implemented on denim jeans substrate of thickness h = 1.6 mm and epsilon(r) = 1.6. With the presented design, measured bandwidth of 5.8% (2.37-2.51 GHz). The axial ratio bandwidth of 80 MHz (2.40-2.48 GHz), and a peak gain of 2.70 dBi has been acquired. A perfect matching is observed between measured and simulated results. This novel integrated design is suitable for all body area network communication systems where flexibility and compactness are desirable.
