Then, when increasedthe bandwidth was slightly slightly toto 1457 MHz MHz = Wg = 0.4 mm.when the Wpthe W3 three mm, mm,maximum bandwidth was was886 MHz atat W= = 0.six mm.mm. when was p mm, 3 the the maximum bandwidth only only MHz Wg at 0.6 mm. This the Wp was was the maximum bandwidth was only 886 886 MHz g Wg = 0.six This scenario indicates a a trade-off among the dimension and gap of the parasiticelements This situation indicates a trade-off involving the dimension and gap in the parasiticelements situation indicates trade-off between the dimension and gap of your Tebufenozide Protocol Parasitic elements and the bandwidth size. As a result, by considering the size, probably the most Abscisic acid Biological Activity optimum dimensions as well as the bandwidth size. As a result, by taking into consideration the size, by far the most optimum dimensions and also the bandwidth size. As a result, by thinking about the size, essentially the most optimum dimensions for the antenna were selected toto be 1 mm and 0.eight mm for Wand Wggrespectively. Table 1 1 for the antenna had been chosen to be 1 mm and 0.eight mm for Wp p and Wgrespectively. Table 1 for the antenna have been selected be 1 mm and 0.8 mm for Wp and W respectively. Table shows the comparison between the antenna performance without and with the parasitic shows the comparison involving the antenna performance with out and with all the parasitic shows the comparison between the antenna performance with out and with the parasitic elements. Based on this table, the bandwidth the antenna elevated significantly when a components. Primarily based on this table, the bandwidth ofof the antenna elevated significantly when in the antenna increased significantly when elements. Primarily based on this parasitic element was added. a a parasitic element was added. parasitic element was added.Table 1. 1.
