TY - JOUR ID - TI - Implementation of a Circular Shape Patch Antenna at 2.4 GHz for Different Wireless Communications AU - Ali H. Khidhir PY - 2023 VL - 64 IS - 1 SP - 205 EP - 214 JO - Iraqi Journal of Science المجلة العراقية للعلوم SN - 00672904 23121637 AB - In this work, the circular patch antenna was fabricated and analyzed. MicrowaveStudio (version 2019) computer simulation technology (CST) was used to design thecircular patch antenna. The material FR-4 was used to build this antenna, using thecomputer numerical control (CNC) method to implement this work. For the purposeof accomplishing this design, the values of the resonant frequency, dielectricconstant and dielectric thickness of the material used as in 4.424, 2.4 GHz and 0.159cm respectively were used as inputs to the CST program to get the said programoutputs for the required antenna radius with the logarithmic function (F) of thecircular patch antenna 1.6909 cm and 1.7415 cm respectively. Practically, the bestvalues for the antenna were obtained in terms of return loss, voltage standing waveratio (VSWR), and input impedance, -25.72 dB, 1.1092, and 54.391 Ω respectivelyat the resonant frequency of 2.360 GHz. Where it were good values compared to theresults of others.
