The frequency spectrum is currently used for many applications and this resource is limited. There is also a growing demand for the use of higher frequencies, resulting from the demand from electronic warfare systems. Therefore, it is necessary to use the high band spectrum. The main advantages of working at high frequencies include more available bandwidth, smaller circuits, less interference with other services, and a less saturated spectrum.1 In this context, ultra-wideband microwave circuits have gained prominence in radiocommunications systems because many applications demand the use of large bandwidths and these kinds of circuits are of great relevance in microwave technology.
