Triple Band CPW-Fed Microstrip Antenna with Hexagonal Shape Slot for WLAN/WiMAX Applications

In this research work, a CPW-fed diamond shaped patch embedded with hexagonal shape slot and L-shape strip attached to it which produces tri-band operation which is suitable for WLAN/WiMAX applications. The proposed antenna has a simple structure and occupies size of 28.5 × 33.125 mm². The parametric study is performed to understand the characteristics of the proposed antenna. The proposed antenna is capable of generating three distinct operating bands 2.12–2.82GHz, 3.33–4.27 GHz, 5.12–7.09 GHz, covering all the 2.4/5.2/5.8GHz WLAN bands and the 2.5/3.5/5.5 GHz WiMAX bands. The various antenna parameters like S-parameters, current distribution and radiation pattern are studied.
