Abstract
In antenna arrays of dual-frequency wireless systems, the beam-forming matching-network may require power splitters that give equal phases at the two outputs, but different unequal power splits at different frequencies. This paper shows that the power splitters can simply be made from a two-section transmission-line transformer in each branch and analyzed by the transmission-line theory
