Abstract :
A new type of a dual-frequency and dual-linear-polarization multilayer stacked microstrip antenna element is presented. The feeding mechanism of the element is aperture coupling for one polarization and direct feeding for the orthogonal polarization. The microstrip element exhibits a wide band of operation, high isolation between ports, and high radiation efficiency for both polarizations compared to other types of elements. A parametric study was conducted using a commercial software based on a method of moments (MoM) algorithm and is presented. A prototype with dimensions based on the simulations was built and tested. The agreement between the measured and numerical results is good.
