Design and Development of Multilayer Dual Polarized Antenna with High Isolation at X- Band for Microwave Imaging Applications

摘要

In this paper, An X-band dual-polarized Edge feed aperture coupled antenna with high isolation is presented. The design is composed of micro strip rectangular patch with slot on the ground is fed by a two orthogonal microstrip lines. Dual polarized antenna is implemented on RT Duroid 5880 & 6010 substrate and proposed antenna results are verified. The measured outcome shows that S₁₁ less than -10 dB and the isolation (S₂₁) between the ports is -30 dB at the X-band. In addition, the cross-polarized discrimination is better than -32dB, with the gain of 8.9dBi. It is concluded that the simulated and measured performance is almost same.
