Enhanced Phase Coherence in Series‐Fed Patch Array Antenna: A Design Method for Uniform Element Spacing With Low Sidelobe Levels

ABSTRACT Microstrip series‐fed patch array antenna (SFPA) is increasingly prominent in millimeter‐wave radar systems. Especially, SFPA with tapered amplitude using Dolph–Chebyshev, Taylor, and Binomial distribution has been developed to reduce a sidelobe level (SLL), which is critical to radar resol...
