Architectures and Components for Single- and Multi-Band Antenna Feed Chain
Specific Seminar - Curriculum 6
Abstract:
The design of single- and multi- band microwave systems is of the greatest interest in several modern applications, such as satellite communication[1] and scientific equipment for universe and Earth science[2, 3].
According to the application, electrical and mechanical requirements change, however, high polarization purity and low losses are common desired features as well as the chance of integrating of different frequency bands in the same system.
As an example, the trend in modern telecommunication satellites is to allocate different services in the same feed working in single or dual polarization in both receiver and transmitter modes[4]. Wide band and polarization purity are key issues also in the design of microwave and millimeter-wave receivers used in scientific surveys, since high sensitivity of instrumentation is necessary[5].
In this scenario, each device composing the antenna-feed chain has to be designed in order to guarantee significant electromagnetic performances and, at the same time, high integration levels. In this talk, we discuss the main architectures and components of passive antenna feed chains. In this contest, the application of Additive Manufacturing technologies is discussed showing its potential and the current trends in the development of radio-frequency front-ends[6].
