Abstract
A partially reflect surface antenna includes a substrate, a reflective sheet and a plurality of supporting units. The substrate has an upper surface formed thereon a signal I/O for receiving and outputting high frequency signal. The reflective sheet partially reflects the high frequency signal and includes an array antenna block located at the surface of the reflective sheet. The plurality of supporting units support the reflective sheet to locate at the upper surface of the substrate and to maintain a predetermined distance between the reflective sheet and the substrate. The area of the array antenna block ranges from 0.31 to 0.8 times of the surface area of the reflective sheet.
