WebThe structure of this modified Butler matrix is discussed in detail, and the explicit design formulas are derived to achieve the arbitrary main beams direction. Using the proposed design procedure, the Butler matrix can provide even broadside and endfire beams. In addition, this structure is employed to design two Butler matrices, which ... A Butler matrix is a beamforming network used to feed a phased array of antenna elements. Its purpose is to control the direction of a beam, or beams, of radio transmission. It consists of an $${\displaystyle n\times n}$$ matrix ($${\displaystyle n}$$ some power of two) with hybrid couplers … See more The antenna elements fed by a Butler matrix are typically horn antennae at the microwave frequencies at which Butler matrices are usually used. Horns have limited bandwidth and more complex antennae may be … See more A typical use of Butler matrices is in the base stations of mobile networks to keep the beams pointing towards the mobile users. Linear antenna … See more • RF switch See more The essential components needed to build a Butler matrix are hybrid couplers and fixed-value phase shifters. Additionally, fine control of the beam direction can be provided with variable phase shifters in addition to the fixed phase shifters. By using the variable … See more A linear antenna array will produce a beam perpendicular to the line of elements (broadside beam) if they are all fed in phase.
