The variants of building one-dimensional and two-dimensional microstrip antenna subarrays, which consist of a small number of elements and are used as elements of sparse antenna arrays, are described. Numerical simulation is implemented with AWR Microwave Office and CST Microwave Studio. Modeling results are compared with experimental results.
This paper proposes a model of the rectangular microstrip antenna based on the integral equation method and thin-wire approximation of a metal patch. A substrate is taken into consideration by inserting values of dielectric effective permittivity in the integral equations. The comparison of the calculated input impedance and resonant frequency with the experimental data and modeling results in commercial...
The paper presents results of research and development of a novel dual band circularly polarized microstrip antenna array with adaptive space-time processing capability for applications in satellite navigational systems GPS/GLONASS/GALILEO. Geometry of the proposed antenna array was optimized for the operation in two frequency bands allocated for satellite navigational systems. The developed array...
