Studying the Effect of Bending on Flexible Multiband Inverted-F Antenna for Wi-Fi/WiMAX Application

摘要

the rapid development and innovative technologies that permit exploration in telecommunication networks and devices inspire us to develop an antenna design that works on four different frequencies. An ultra-thin flexible inverted F- antenna has been developed to provide four WiMax/Wi-Fi bands. The small and thin size of the antenna makes it very easy to fit in any space. The design works on 2.4 GHz, 3.4 GHz, 5.2 GHz and 5.8 GHz. The proposed antenna was printed over a Kapton polyimide substrate with a relative permittivity 3.4 and thickness 50 µm. All the antenna parameters are provided, such as S11 and Radiation pattern. Moreover, we discussed the effect of the bending on the antenna to evaluate its effect on the antenna performance.
