Abstract :
This paper reported a broadband 8times16 retro-directive array for millimeter-wave applications. The array element is a proximity-coupled dual-ring antenna with a bandwidth of 33.7% (31-42.8 GHz). The antenna is used to build a 4times4 retrodirective array as a sub-array. Then the sub-arrays are assembled to form an 8times16 array. The design method of the arrays and the measured performances from 32 GHz to 40 GHz are presented.
