A Compact Slotted Antenna with Two Parallel Stubs of Vertical Open-ended in Nature for Application in Wireless Communication

An antenna fed by the transmission line of microstrip in nature with slotted characteristics having two parallel stubs of open-ended in nature which are emerged simultaneously from the inner edge of the middle top portion of the ground plane of rectangular slotted in nature is proposed in this paper. The antenna which is proposed is comparatively having smaller physical structure of size 24×28 mm

which produces two simultaneous resonances at 1.81 GHz and 5.91 GHz respectively which are essentially operating bands of DCS/PCS and WLAN systems. Both the resonating bands exhibiting the percentage bandwidths of 9.94 and 8.75 respectively. The peak gains at the two resonating frequencies are 3 dBi and 3.5 dBi respectively, which are sufficient for the application of DCS/PCS and WLAN. The antenna which is proposed stable patterns of radiation and gain which is appropriate in nature.
