Simulation on Circularly Polarization Cotton Textile Antenna for Wireless Communication System

The fast development of the wearable textile antennas in recent times due to the modern miniaturization of the electronic devices, which included all civil and military fields. It is a part of the clothing used for the communication purposes such as tracking, navigation and fitness, as well as for medical purposes inside hospitals. In this paper, the design of the wearable textile antenna that operates at 2.4 GHz for wireless the communication system is discussed. The antenna is proposed with plus-shaped is employed on the substrate of cotton textile with dielectric constant, er = 1.6, the tangent delta loss, δ = 0.0400 dB and the thickness of the substrate is h = 0.27 mm with a single microstrip feed line impedance at 50 Ω. The center frequency at 2.4 GHz with the reflection coefficient of −20.01 dB, the gain of 7.44 dB and the efficiency is about 56.79% of the proposed antenna. The left-hand circular polarization (LHCP) has obtained in the cotton textile antenna as AR is successfully achieved below 3 dB. CST used to the design and the simulation results of the antennas performance. The proposed cotton textile antenna is suites to be applied for the future wireless communication system.
