Linearly Tapered Meandered Slot Flexible Antenna for DCS/ISM/WLAN/WiMAX Applications

A flexible CPW-Fed linearly tapered meandered slot (LTMS) antenna is proposed for DCS/ISM/WLAN/ WiMAX Applications. Polyimide material is used as substrate to achieve flexibility. Linear tapering and meandered slot is considered in order to enhance the bandwidth and gain of the LTMS antenna. The LTMS antenna resonates at 2.28GHz (1.7-2.66GHz) and 5.58GHz (4.6-7.3GHz) multi-band frequencies with a -15.6dB and -35.1dB reflection coefficients respectively. The 3D-gains are observed 2.67dBi and 4.52dBi. In order to check the compatibility with flexible devices bending deformation is also checked with the proposed LTMS antenna. Very slight deviations are observed in antenna performance in bending state and the performance of the antenna will not be deviated with the planar state.
