Microstrip directional couplers are made on microwave substrates, which consist of various dielectric materials. With a decrease in the operating frequency, the dimensions of the coupler increase, and more material is required for their manufacture. To reduce the consumable material, you can use different approaches to miniaturize the couplers, this will reduce the size of the device while maintaining its characteristics. So this article presents the results of research to reduce the occupied area of a flat crossover tuned to a frequency of 1 GHz. The size reduction process consists in the simple replacement of microstrip segments with a length of ?/4 with original electrodynamic structures, which are high-resistance segments with the U symbol. With the help of these structures, it was possible to reduce the size of a standard crossover. by 70%, with a decrease in bandwidth by 10%. As a result, when miniaturizing directional couplers, it is necessary to find a compromise, which is that when the size of the device decreases, the frequency band decreases and the losses increase. The proposed approach to reduce the area of the device, it is possible to use for other microstrip devices.
