Currently, there is an active development of communication in the millimeter wavelength range due to the occupancy of lower frequency bands. In addition, the millimeter range allows to transmit the amount of information at a higher speed, having a high bandwidth. However, in this range there are high requirements to the accuracy of manufacturing and processing of microwave devices to preserve their electrical parameters. Consequently, the use of some transmission lines in the design of antenna arrays (AA) does not provide the necessary efficiency. This necessitates the use of a transmission line whose fabrication does not impose technological problems that affect its performance.

The purpose of this work is to provide a mock-up of a millimeter-wavelength antenna array using a novel transmission line based on gap-waveguides.

As a result of this work, a waveguide adder path for a millimeter wavelength range millimeter-wave antenna array based on gap-waveguides is developed in an electrodynamic simulation program. Based on the model, a mockup of the receiving and transmitting waveguide path is created and a dual-band antenna array is assembled. The radiating part is microstrip coupled resonators in the receiving and transmitting bands. Measurements of the electrical parameters of the received layout are carried out, according to the results of which the directions of improvement of the design are determined.

Implementation of the described design of the addition path for phased antenna arrays in the millimeter wavelength range will significantly facilitate the production technology, thereby reducing the time of assembly of antenna arrays and the cost of manufacturing.
