The definition of antenna management as an element of the urban environment is given. As part of the urban environment, an electromagnetic environment has been identified that is subject to protection and rational use. The technological factors for the development of antenna economy are highlighted: technological development of increasingly high-frequency ranges based on the creation and use of new materials; development of computer and information technologies for signal processing and its distribution in communication networks; competition and addition in communication systems from wire means.
The following are accepted as signs of periodization of the development of the antenna economy of cities: classification of radio frequencies in accordance with the recommendations of the International Telecommunication Union; applied methods of signal generation and processing; the presence in the composition of communication devices of specialized processors that process the signal. It is shown that the evolution of antenna economy as an element of the urban environment occurs under the influence of two substantial factors: an increase in the amount of information and an increase in the speed of its transmission.
The main method for resolving such a technical contradiction is to increase the frequency and expand the bandwidth of the radio channels. At the same time, the geometric parameters of the antennas are reduced down to the microcircuit element, and the increase in the communication range is ensured by the development of relay systems, including fiber-optic communication lines, satellite and quasi-satellite communications, implemented using unmanned aerial vehicles located in the stratosphere. The evolution of the electromagnetic environment of cities occurs in the direction of radiation growth in the millimeter and submillimeter ranges
