Hexagonal Slot Antenna With Dual Band Notched Characteristics For Uwb Applications

Abstract

Printed hexagonal slot antenna with dual band stop characteristics for ultra wide band applications is presented in this paper. The basic antenna comprises U - shape radiating patch and ground plane with hexagonal slot. By proper alignment and use of hexagonal slot additional resonances and much wider impedance bandwidth is obtained. By embedding inverted L - shape parasitic stubs at the upper edge at the hexagonal slot,obtain the desired band rejection characteristics for WiMAX and WLAN respectively. The operating frequency of proposed antenna is r anged from 2.76~11.07 GHz w i th a dual band rejection from 3~4GHz (for WiMAX) and 5~6 GHz (for WLAN).The designed antenna is fabricated on a FR - 4 glass epoxy substrate having dielectric constant of 4.4 with overall dimensions of 28 x 28 x 1.6mm 3 . https://www.ijiert.org/paper-details?paper_id=140915
