Active phased array antenna with parallel feeder excitation at 3.7 GHz

Abstract

The article discusses the electromagnetic ra- diation level reducing in 5G telecommunication systems used in modern campuses of medical clinics, in order to ensure the correct operation of a number of medical devices and systems. The use of a phased antenna ar- ray (PAA) with beam scanning technique as part of a medical telecommunication system is proposed. A sim- ulation of the proposed rectangular phased antenna ar- ray in the form of 0.5∗λ spaced 7x7 elements matrix was carried out. Matrix elements are constructed in the form the printed circuit board. Dipole-folded an- tenna element is used to increase the manufacturability of the system. Moreover, the receiving side is made in the form of three separate space sparse receivers site, but not in the form of a single one. The simulation was carried out by means of the Matlab IDE Phased Array System Toolbox. The proposed approaches made it possible to reduce the level of electromagnetic radia- tion in the 5G telecommunication system in two ways: by reducing the overall level of radiation compared to an omnidirectional emitter and by using the beam scan- ning technique of the proposed receiver structure.
