PHASED ARRAY ANTENNA FORMED AS COUPLED DIPOLE ARRAY SEGMENT

摘要

PROBLEM TO BE SOLVED: To form an array in a manner that makes such arrays more easily repairable if one element is defective. SOLUTION: A phased array antenna includes a substrate that is segmented into a plurality of array tiles. An array of dipole antenna elements is formed on the substrate with each dipole antenna element positioned on a respective one of the array tiles. Each dipole antenna element includes a medial feed portion and a pair of legs extending outwardly therefrom. Adjacent legs of adjacent dipole antenna elements include respective spaced apart end portions forming a gap between the respective end portions and defined by separate tiles. A capacitor coupler is positioned at each respective spaced apart end portion of adjacent legs and bridging a gap for capacitive coupling respective spaced apart end portions of respective adjacent dipole antenna elements together.
