ABSTRACT: In this paper, two different methods were used for investigating the RF characteristics
of three types of textile materials. Goch, Jeans and Leather substrates
were studied. A microstrip ring resonator method and DAK (Dielectric
Assessment Kit) method were used. Bluetooth antennas were designed and
fabricated using these substrates. The results were compared for the two methods.
The bending effect of these antennas on its impedance characteristics
due to human body movements was also studied. Finally, all antennas were
simulated by CST simulator version 2016, fabricated using folded cupper and
measured by Agilent 8719ES VNA. The measured results agree well with the
simulated results.
