Abstract
In this paper, we investigated the effect of tilting and bending of an 2.45GHz ISM band embroidered dipole array antenna due to the human body movement. The antenna characteristics showed larger variations in tilting on the X-axis than the Y-axis. The antenna gain varied by 0.25[dB] when the antenna tilted by 3.5°. As tilting angle increased the operating frequency(fo) showed decreasing tendency and the return loss(S11) showed increasing tendency. The antenna characteristics also showed more variation in bending on the X-axis than the Y-axis. As bending the antenna the antenna characteristics affected much more in bending on the X-axis than the Y-axis. The antenna gain varied by 3.73[dB] as the curvature(1/R_rad) increased by 0.04[mm-1]. As it bended more the operating frequency(fo) showed decreasing and then increasing tendency and the return loss(S11) showed increasing tendency.
