ABSTRACT:
The present invention relates to a microstrip reflective array antenna adopting a plurality of U-slot patches. The microstrip reflective array antenna comprises a reflective disk, a horn antenna and a support. The reflective disk is adapted to reflect microwave signals wherein a plurality of square patches are disposed on the upper surface of a first substrate and a plurality of U-slot patches corresponding to the square patches are disposed on the upper surface of a second substrate. In addition, the lower surface of the first substrate is stacked on the upper surface of a second substrate. The horn antenna is adapted to receive the microwave signals from the reflective disk, and the support is adapted to hold the horn antenna directly above the reflective disk.
