This research study delineates the design, simulation, and performance assessment of four patch antennas for Ka-band wireless applications at 25 GHz. The four different designs use the Rogers RT6002 substrate material. It is 0.6 mm thick, has a dielectric constant of 2.94, and a loss tangent of 0.0012. The antenna is engineered and modeled by CST software. The reflection coefficient (S11), voltage standing wave ratio (VSWR), Gain, directivity, bandwidth, and efficiency were obtained from the antennas. Design 1, 2, 3, and 4 achieved the S11 and VSWR are − 11.14 dB, − 19.5 dB, − 14.87 dB, − 48.52 dB and 1.76, 1.23, 1.44, 1.007. Also, Gain and directivity are achieved at 6.13 dBi, 5.94 dBi, 6.01 dBi, 6.22 dBi and 6.91 dBi, 6.71 dBi, 7.1 dBi, 6.86. Both antenna’s feedline impedance matching is 50Ω. The efficiency of the antenna design 1, 2, 3 and 4 are 88.71%, 84.05%, 84.6% and 90.67%, respectively. The primary purpose of this research is to improve the return loss and achieve an acceptable VSWR. Additionally, increasing the bandwidth can enhance the antenna’s gain directivity and impedance matching (50 Ω). The design-4 bandwidth is 1.4 GHz, significantly superior to designs 1, 2, and 3. The antenna’s overall performance renders it appropriate for forthcoming 5G applications.

摘要

This research study delineates the design, simulation, and performance assessment of four patch antennas for Ka-band wireless applications at 25 GHz. The four different designs use the Rogers RT6002 substrate material. It is 0.6 mm thick, has a dielectric constant of 2.94, and a loss tangent of 0.0012. The antenna is engineered and modeled by CST software. The reflection coefficient (S11), voltage standing wave ratio (VSWR), Gain, directivity, bandwidth, and efficiency were obtained from the antennas. Design 1, 2, 3, and 4 achieved the S11 and VSWR are − 11.14 dB, − 19.5 dB, − 14.87 dB, − 48.52 dB and 1.76, 1.23, 1.44, 1.007. Also, Gain and directivity are achieved at 6.13 dBi, 5.94 dBi, 6.01 dBi, 6.22 dBi and 6.91 dBi, 6.71 dBi, 7.1 dBi, 6.86. Both antenna’s feedline impedance matching is 50Ω. The efficiency of the antenna design 1, 2, 3 and 4 are 88.71%, 84.05%, 84.6% and 90.67%, respectively. The primary purpose of this research is to improve the return loss and achieve an acceptable VSWR. Additionally, increasing the bandwidth can enhance the antenna’s gain directivity and impedance matching (50 Ω). The design-4 bandwidth is 1.4 GHz, significantly superior to designs 1, 2, and 3. The antenna’s overall performance renders it appropriate for forthcoming 5G applications.
