| Abstract: | A new dual-frequency and dual-polarization coplanar aperture-coupled microstrip antenna is introduced in this paper. The operation frequencies of the antenna are 2.1GHz (L-band) and 8.6GHz (X-band), and the inverse feed form is employed. The radiation unit cell of the dual-polarization microstrip antenna in L-band and X- band is analyzed by the finite-difference time-domain method (FDTD). A prototype antenna with unit-cell array in L-band and the unit-cell array in X-band is made, and the measured curves are obtained. |
