Microstrip Implementation of Crossover on Artificial Transmission Lines

It is known that the dimensions of the devices vary depending on the operating frequency. If we look at the decimeter frequency range, we will find that devices in this range take up a lot of space and require miniaturization for some applications. Therefore, in our work we considered such a device as a crossover, which is used instead of two intersecting lines in one layer. The crossover is 2.8 times smaller than the traditional design. This result was achieved through the use of artificial transmission lines installed instead of the usual quarter-wave sections. Electrodynamic analysis and field experiment allowed us to confirm the effectiveness of the proposed device design. As a disadvantage for our device, we can single out a decrease in the operating frequency band by 11%.
