Abstract
In the modular feed for a phased array antenna, the advantages of a series-type feed and a corporate-type feed are combined to increase the system efficiency and the operating bandwidth of the modular feed. Feed modules having a stage of power bifurcation are used to feed array modules having a general series-type feed configuration. The array modules may be interchangeable, and the feed modules may be interchangeable, which decreases production costs and system complexity.
