Abstract

This paper introduced the 4×4 Butler matrix as the beamforming network combined with 4 linear antenna arrays to produce four narrow steerable beams. The designed was aimed for resonance frequency 900 MHz in application of GSM base station transmitter. The position of radiation patterns achieved by this project then compared with the theoretical calculation and simulation using the PCAAD simulation. The resultants of signal strength by four beams were indicated low level that may caused by loss factor to the components used.
