Design of notch-enhanced compact printed antennas for 5G communications

The design of a frequency notched antenna for 5G base stations is presented in this paper. In particular, given the considerable number of constraints on the antenna performance, the problem can be defined as a multi-objective problem. The reduction of such complex problem into a single-objective one allows the use of well known optimization strategies like evolutionary algorithms, capable of determine a set of valuable tradeoff solutions. Preliminary numerical results are discussed in order to validate the proposed design procedure.
