Six-channel broadband inhomogeneous microstrip power divider for communication antenna array

Abstract

Problems ofthe design and computer simulation of inhomogeneous microstrip power divider for octave L-S,frequency band for the base station antenna array of the radiocommunication system are considered in this paper. Broadband matching of the antenna array and synthesis of the optimal matching networks are discussed. Theory base of muthematical analysis ofthe broadhand multiport divider, microstrip rea/iza/ion and resdts of computer analysis and experimental investigations are presented. Influence of some possible dismatching of the real microwave array on signal antenna distribution is discussed.

Scattering matrices of multiport radio devices

“…A solution of the broadband multiport antenna matching problem for given antenna pattern may be carried out with base of design algorithm with use of ordinary scattering matrix (Fig.1,c). [1][2][3]5,6]: 1. Determination of amplitude-phase antenna distribution for given antenna pattern.…”

“…One of the classic problems in antenna theory is a design of an optimum equalizer to match an arbitrary multiport load (antenna array) to generators [3,5]. The solution of this problem may be carried out by use of different scattering matrices normalized to diagonal or multiport networks [1][2][3][4][5][6][7][8][9].…”

Wideband Multiport Matching Phase I: Single-Feed Multiport Antennas

“…For example, Czawka [10] offers broadband microstrip uncouplers for multiport complex loads. Closely allied with this SIMO design is a six-channel wideband power divider by Czawka [11]. Jarmasz and Martens [24] apply a variant of this decoupling approach to wave digital filters.…”

Low Loss High Power Air Suspended Stripline Power Divider for High Power Division Sub-Systems Applications

“…The increased need for high power microwave components has become essential in modern communication, radars and satellite systems [1]. Power divider is one of the most basic highpower components which are widely used in high power circuits and systems, such as antennas [2][3][4] amplifiers [5,6], six-port circuits [7], push-pull circuits [8].…”
