Abstract

The research presents the design of a meander line patch MIMO antenna for synthetic aperture radar applications, which resonates at 1.3 GHz on L-band and 3.05 and 3.8170 GHz on S-band frequencies. The MIMO antenna is built on a FR4 substrate with a dielectric constant of 4.4 and a thickness of 1.6 mm, and it is designed using the ANSYS HFSS software program. This design focuses on optimizing radiation patterns while remaining compact and simple to fabricate. The proposed antenna has a return loss of below -20 dB, VSWR < 1.5, an axial ratio of < 3dB. The simulation results illustrate how well the MIMO antenna effectively performs for SAR applications, such as vegetation monitoring, soil moisture, GPS, and disaster management.
