This paper presents a novel, compact, fractal shaped, unequal length branch-line coupler for dual band applications. The proposed planer topology exhibits compact size as well as dual band characteristics with quadrature phase difference centered at 900 MHz (GSM band) and at 2.4 GHz (ISM) band, with...
