Design research of wearable textile Antena

Abstract

In this paper comprehensive analysis and design of textile antenna is presented. Low dielectric constant of textile material makes them suitable to be used as substrate. The proposed antenna is fabricated on jeans substrate having dielectric constant of 1.6. The proposed textile antenna has hexagonal shape with microstrip line feed.U shape slot on the patch and defected ground structure is incorporated in the design to obtain desired passband and stopband. The dimension of proposed hexagonal patch is 6.44 mm and its area is 108mm2 which is very compact as compared to previous works.This antenna can be used in two frequency bands one is centered at 3.9 GHz with bandwidth of 2.5 GHz and another is centered at 8.6 GHz with bandwidth of 2.4GHz.Along with these passband there is one stop band in the frequency range 5.1GHz to 8.1 GHz. Due to wide bandwidth this antenna can also be called as an ultra wideband antenna with notch band to avoid electromagnetic interference with WLAN (5.1 -5.8 GHz) and satellite application.
