Abstract:
ABSTRACT This paper deals with miniaturization of wearable electro-textile antennas by use of Minkowski fractal geometries. Tuning holes give desired result when change the position of holes. In this case, polyester fabric material has been employed as dielectric medium. CST simulation results provides a gain of 6.897dB & Directivity 8.15dBi with an impedance bandwidth of 82 MHz by applying Minkowski fractal geometry to the antennas, miniaturization is achieved. Impedance and radiation characteristics of 2.45 GHz wearable antennas in close proximity to human body are discussed in this paper. There are two major features causing the capacity increase for the proposed system: 1) the high efficiency of the electro-textile antennas that can be seamlessly embedded into human clothing; 2) significant system diversity gain due to the wide spacing among antennas in the distributed body-worn system. Antenna are designs for WLAN application Antenna structure is designed at a height 2.85mm from the ground plane by using Computer Simulation Technology (CST) software. The operating frequency of the design antenna is 2.45 GHz. Antenna simulation results are carried out over the frequency range of 1.0 GHz to 6GHz for Flectron antenna under investigation. The simulation result reveal that the Flectron wearable antenna operating frequency of 2.538GHz,2.395GHz, 2.351GHz and 2.340Ghz for zeroth,1st ,2nd and proposed iteration respectively. Corresponding -10dB return loss bandwidths are 115MHz, 109MHz, 104MHz and 82 MHz respectively. Keywords: Fractal Antenna, Antenna Tuning.
