✦ Synopsis
The design and development of a shared-aperture dual-band, dual-polarized, dual-aperture coupled rectangular microstrip patch antenna element is presented, which is suitable for portable very small aperture terminals. Detailed parametric studies of the locations of orthogonal coupling slots and their influences on the isolation and impedance bandwidth of the antenna element are performed. The experimental results are presented. The prototype dual-band dual-polarized antenna element achieves a 21% input impedance bandwidth at the S-and C-bands. The design and development of a four-element array with such an antenna element is also presented.
