Abstract

Beam forming techniques are used to increase the efficiency of using frequency. In this paper we design and implement Butler matrix to be used for ISM band. The implemented Butler matrix has the insertion loss of maximum 6.7dB and the maximum phase shift error of $-6.51^{\circ}{\sim}7.17^{\circ}$ over 2.4~2.485GHz.

주파수 이용효율을 높이는 방법으로 빔포밍 기술을 사용한다. 본 논문에서는 무선랜 주파수 대역에서 RF 빔포머로 사용할 수 있는 버틀러 매트릭스를 설계 및 제작하였다. 구현한 버틀러 매트릭스는 2.4~2.485GHz의 주파수 범위에서 삽입손실은 최대 6.7dB, 최대 위상천이 오차는 $-6.51^{\circ}{\sim}7.17^{\circ}$ 갖는다.
