摘要：

Technique to find Direction Of Arrival (DOA) has been promisingly constructed by smart antenna technology. It consists of array antennas and signal processing unit. Because of the limitation of space in commercial products, the size of antenna array should be designed with the smallest dimension. Also the processing unit is expected for low complexity and expense. Most of DOA finders were recently proposed employing linear array in which the size is linearly increased by a number of antenna elements. Also the processing units were fully comprised with high level of computation. In this paper, the low profile of 2.4 GHz DOA tinder is proposed. The DOA finder is designed in the compact size of 2x2 array antennas. Using modified Butler matrix, the processing unit is very simple in which it can be handled by any economic microprocessors. The experimental results confirm the success of proposed DOA finder.
