Abstract
In the suggested manuscript, an antenna functional over an ultrawide band with a small geometrical configuration and simplified structure is given. The recommended antenna is designed for the Roger 6002, having overall measurements of 40 mm × 30 mm × 1.52 mm. The wideband is obtained after loading stubs and etching slots from the basic antenna design. In order to improve the antenna's performance further, an FSS sheet is designed. The sheet of FSS is placed behind the antenna to reflect the antenna's backward radiation and improve antenna gain. In the results, the gain of the antenna improved from 4.5 dBi to 9.5 dBi. The resultant antenna loaded with FSS is capable of operating over UWB ranging from 3.4 to 9.8 GHz with stable gain throughout the functional bandwidth. The hardware model is manufactured and tested to validate the estimated results achieved from HFSS (High Frequency Structure Simulator). Moreover, the recommended work is differentiated in the form of a table with literature. The compact size, wideband, high gain and stable performance of proposed antenna system over-performs the literature work and makes it protentional candidate for the UWB system requiring high gain.
