Abstract:

This paper introduces the power dividers in the phased array feed network application,which USES a transmitter power by power splitters connected to the antenna array,compared with the traditional one transmitter corresponding connection in antenna array antenna feed mode,mainly has the following advantages:the impedance of the antenna array in the transmitter port have been better features,improved the original traditional pattern due to the coupling of severe may lead to individual array antenna impedance mismatch in so serious that the transmitter can't work normally;can make the antenna array antenna spacing have larger adjustment space,make the antenna array has better scanning features.

Key words: power divider phased array impedance characteristic
