Abstract
The design and analysis of a high-performance dual-polarized perpendicularly fed microstrip patch antenna are presented. The planar balanced feeding technique has been evolved to a highly isolated nonplanar method for exciting a dual-polarized microstrip patch antenna. Reducing the number of parallel dielectric and ground plane layers improves the isolation between polarization and increases the antenna scan capability. The simulation and measurement results of the proposed antenna are presented. The proposed antenna possesses high-performance electromagnetic characteristics. Input isolation of better than 52 dB between orthogonal polarizations in the entire frequency band of 2.7-2.9 GHz and cross-polarization level of better than -32 dB have been achieved in the measured results.
