Implementation of Dual Band Slot Antenna for Wireless Applications

This article presents a compact dual-band octagonal shape slotted formation patch antenna for WLAN/WiMAX and X band wireless applications. Proposed design consist the circular slotted radiating section with six octagonal shape and two hexagonal shape elements to produce the resonating bands at 3.12-6.34 GHz (WiMAX: 3.5 GHz, WLAN: 5.8 GHz) and 7.48-14.87 GHz (X band: 8-12 GHz) respectively. Antenna is printed on Forgotten Realms 4 (FR-4) dielectric substrate material. The ground plane and feedline are designed in trapezoidal shape. The antenna is designed with size compactness of 29. 5× 22× 1.6mm ³ and analysed regarding simulated results of return loss, radiation patterns, gain and radiation efficiency. Simulated results are consistent and stable at generated operating bands.
