Abstract

Nowadays, communication systems are moving towards higher data rate transmission. MIMO is one of the techniques which is new and widely explore by the rcs~.:archcrs . MIMO concept can achieve by implement Beam forming Network into the system. This project will design the beam forming network by using Butler Matrix com:cpt. This paper presents the design, simulation and fabricate of a fourport Butler matrix to feed an any antenna for Wireless Local Area Network (WLAN) at 2.4 Gll z. The design process begins with calculation of design specifi cati on such transmission line, width and length. The Butler matrix consists o r the main components, which is the hybrid coupler, crossover and phase shifters. Then, the design circuit will be simulate using Microwave Office Software 2004. Tht: design wi ll be (~bricated by using an etching technique and will be implemented on fR4 board. Results from simulation and fabrication is then being compared in term of return loss (S ii), transmission coefficient (Sji), isolation (Sij) and the phase difkrence between each port.
