Phased array irradiator for a new generation of wireless data transmission system

Nowadays, a necessity to increase, in the first place, the communication channel capacity and data rate is caused by a continuous increase in the needs of the users of the telecommunications companies in the resource-intensive exchange of content (e.g. streaming high quality video), what is frequently reported. Mobile communication systems of 3rd and 4th generation (3G and 4G) are practically depleted in terms of rise of data transmission speed. To find the solution, it is necessary to make a jump from traditional centimeter radio waves range to the millimeter range. In this regard, the construction development of waveguide-slot radiators for building the phased array of equipment of 60 GHz wireless transmission is being discussed. Waveguide-slot radiator is based on the standard WR-15 waveguide of millimeter range. The Ansys HFSS software was used for electromagnetic modeling of resonant and nonresonant waveguide-slot radiators. The radiation patterns of noted radiator types, the frequency dependencies of the standing wave ratio and the gain frequency dependencies are shown. The frequency passband of proposed designs was determined. The acquired results show that synthesis of multi-functional wideband antenna devices is possible by simple constructions usage.
