Embodiment Construction
[0015] refer to figure 1 , in the embodiment described below, S / Ku dual-frequency co-aperture linearly polarized phased array scanning antenna includes: distributed on the antenna mounting plate by a circular array array S-band dipole antenna (1) and by The area array is distributed in rows and columns and covers the Ku-band microstrip patch 2 on the dielectric board. Ku frequency band microstrip patch 2 arrays are distributed on the cross rectangular plane of the dielectric plate to form Ku frequency band microstrip array, and Ku frequency band microstrip patch 2 arrays are distributed on the dielectric plate cross cross rectangular plane to form Ku frequency band microstrip array The Ku array is a 24×24 cut-angle array, and the Ku array with a cut angle of 4×4 at the four top corners is attached to the circular-aperture antenna mounting plate; a square array composed of four S-band dipole oscillators Embedded in the Ku-band microstrip array, the other arrays of S-band dipol...
