Abstract

The design and testing of an X-band stacked microstrip antenna subarray for dual-polarization applications are introduced. The radiation element is excited by two approaches separately for the orthogonal polarization operation, one of which is the coplanar microstrip line, while the other is through an H-shaped slot. The measured results of S-parameters and radiation patterns of the array are presented, showing a bandwidth of 20% for VSWR≤1.5 and good radiation characteristics.
