Textile linear polarization reconfigurable ring slot antenna for 5.8 GHz band

In this paper, a textile linear polarization reconfigurable antenna for 5.8 GHz band is proposed. It radiates linearly polarized wave which can be controlled in the range of angles ± 30° with respect to the longitudinal axis of the antenna with maximum radiation in the perpendicular direction to the antenna plane. Measured results prove that the proposed antenna achieves at least impedance bandwidth of 11.2 % (angle 0°) for the reflection coefficient less than -10 dB and according simulation achieved the simulated gain between 6.5-7.5 dBi in the perpendicular direction to the antenna plane.
