In this paper, we have presented the IR-UWB tapered slot antenna suitable for narrow space inside the building that is aware of the position of the target. The designed tapered slot antenna is able to induce 25% or more of the operating frequency bandwidth set by the FCC through the change in the physical length of the slot antenna
The end-fire radiation pattern has a directional characteristic. The UWB applications have been expanded by miniaturizing the conventional UWB antenna.
The proposed tapered slot antenna is simple to manufacture because of low precision dimensional tolerances. It has light weight and unlimited bandwidth.
The width () and length () of the antenna is 52mm and 55mm respectively. The simulation result shows appreciable output for bandwidth of 4.1 GHz (2.3∼6.4 GHz). The gain of the antenna at 3 GHz, 4 GHz and 5 GHz is 5.18 dBi, 5.37 dBi, and 7.05 dBi respectively. This shows that gain is increasing with the increase of frequency.
The measured return loss of tapered slot UWB antenna has been obtained for 3.93 GHz bandwidth at 3.26∼6.99 GHz and VSWR is less than 2.
Hence, the proposed antenna has shown sufficient broadband characteristics and is suitable for IR-UWB applications for positioning of objects.
