In this paper, a simple planar design for a symmetric four-port crossover is presented. The proposed crossover is derived from a microstrip patch antenna with a set of two orthogonal feeds. Electrical length of the microstrip patch antenna is increased by incorporating slots achieving a frequency shift to the lower side. The slot in the patch antenna is derived from fractal geometry, which allows three stages of iteration. Isolation better than –15 dB and transmission 0 dB is observed in the frequency range of interest. The proposed crossover is a potential candidate for Butler matrix in beamforming applications. © Springer India 2016.
