Abstract
In this paper double equilateral U-shaped defected ground structure (DGS) units are applied to relize a size reduced microstrip crossover for Butler matrix application. By embedding the DGS units the size of the microstrip crossover at 900 MHz can be reduced by 14.6% compare to conventional design.
