Dual-Beam Microstrip Array Antenna

Abstract

Microstrip array antenna similar to one described in "Parallel/Series-Fed Microstrip Array Antenna" (NPO-18678), except one array produces two off-broadside beams with no additional complication of feeds. Adjacent elements spaced and phased to radiate coherently in desired beam squint directions. In original application, two beams used in airborne synthetic-aperture interferometric radar to measure along-track and cross-track velocities simultaneously. Other potential applications include multiple-beam communications and tracking of aircraft at airports.
