Design and fabrication of UWB microstrip Antenna on different substrates for wireless Communication system
(Institute of Electrical and Electronics Engineers Inc., 2022) Ahmed, O.; Thaher, R.H.; Ahmed, S.R.
A new shape of microstrip antenna is proposed that operates in the 5G Sub band with size 26times 30times 1-6)mm3 ' and the effect of changing the suberate on the performance of the antenna was Investigated; the antenna is Installed using the Roger 8850 Substrata with relative dielectric Constant in_mathrmr=2,2 and loss tangent tan partial=0.009 The Effect of Changing the Substrate t_0in_r=4.3, in_r=6,15) is studied, it is found that these substrates affect the return loss (S11), gain, and group delay. It is found that in_r=2,2 provides better return loss and group delay, whereas the Substrate with in r=6,15 gives better gain; therefore, the Substrate selection depends on the required performance factor. The antennas were fabricated using Rogers Substrata with a relative dielectric constant of in_r=2,2 and tested using the Vector Network Analyzer; it was found that the Simulation and experimental results are in reasonable agreement. © 2022 IEEE.
