Dual-Band Flexible Antenna for WLAN/WiMAX Applications

Aim: This paper presents the development of Co-Planar Waveguide (CPW) fed dualband, compact, and flexible antenna. The antenna is designed on flexible substrate jeans; so, it is suitable for wearable applications. Objectives: The proposed antenna generates dual-band at 3.36GHz-3.61GHz and at 5.01 GHz-5.18 GHz. The antenna has a compact size of 40x30 mm². The antenna consists of a rectangular patch having a slot which is responsible for the first band and slot in the ground plane which is responsible for the second band. Methods: By optimizing the dimensions, the antenna gives dual-band at 3.5 GHz and 5.1 GHz with impedance bandwidth of 250 MHz and 170 MHz, respectively. The performance of the antenna such as gain and radiation pattern over the operating band has been also discussed. Conclusion: This proposed antenna with the first band at 3.5GHz is suitable for Wi-MAX (Worldwide Interoperability for Microwave Access) and second band at 5.1GHz is suitable for Higher Wireless Local Area Network applications (WLAN).
