Miniaturized Crossovers Using Transmission Lines with Open Stubs for Wi-Fi

In this paper, the design and testing of a crossover with reduced area using microstrip technology for Wi-Fi applications in the band 2.45 GHz is presented. The proposal topology uses the standard FR-4 substrate with 31 mils of thickness, and it allows a size reduction of 45.55% without fundamentally altering the frequency response of the device.
