A dual-band microstrip crossover and its miniaturization

This paper presents a dual-band microstrip crossover and its miniaturization. The proposed dual-band crossover works at 0.9 / 2.45 GHz, and the miniaturized crossover reduced 68% of the overall area of the original design. Moreover, analytical design equations are derived using the even-odd mode method. The final explicit design equations are concise. To verify the design concepts, a miniaturized dual-band crossover working at 0.9 / 2.45 GHz is simulated. The simulation results agree well with the concept.
