An analysis of the mutual coupling effects between a finite phased array of dipoles and its feed network is presented. The feed network is typically a corporate feed consisting of split-tee power dividers cascading to form a certain power distribution over the aperture. A simple iterative approach is used to solve for the interaction between elements and feed. The radiation impedances of a finite dipole array are first found for a given voltage excitation. These radiation impedances are then used as loads for the feed network, and n + 1 port network prohlem is analyzed. Due to the interaction between the feed network and the dipoles, the antenna parameters such as mismatch, antenna pattern, and gain are all affected. These effects can be determined from the analarray with a corporate feed are given to show the resultant voltage standing-wave ratio (VSWR) of the feed and pattern degradation due to the mutual coupling effects.
