Abstract:
|
A novel wearable dipole antenna at 325¿MHz resonance frequency is presented in this article. A felt fabric with permittivity 1.2 and thickness 0.7¿mm is used as a substrate. The proposed design is validated by comparison of 3D electromagnetic simulations and measurements. The obtained results correspond to S11 < -18¿dB and a gain 1.5¿dB at resonance frequency, with 49% efficiency and a 20¿MHz bandwidth. Moreover, the effect of bending of the e-textiles under realistic scenarios is also studied. The measured results show that by changing the radius of bending from 32.5 to 3¿cm, the resonance frequency is shifted up 10¿MHz with a sensitivity of 0.285¿MHz/cm. |
