A power divider with 55% overall compactness in size compared to the conventional Wilkinson power divider is presented using a defected microstrip structure. The proposed circuit is reciprocal and it divides and combines input power with less than 1 dB insertion loss. This compact power divider/combiner demonstrates a wide operational fractional bandwidth of 83%. To the best of the authors' knowledge, this is the best-reported compactness achieved in a power divider using only a defected microstrip structure.
