“…On the top layer there are the antenna elements, referred to hereinafter as dielectric-1 (Arlon AD255 with dielectric permeability ε = 2.55 and thickness of 2.032 mm), ground (copper), a dielectric binder-2 (FR-4 with dielectric permeability ε = 4.34 and thickness of 0.1 mm), ground (copper), dielectric-3 (Rogers 4003 with dielectric permeability ε = 3.55 and thickness of 0.305 mm), feeder lines (copper). The location of the antenna elements and the feeder system on separate layers allows reducing the electromagnetic interaction between them [11,[17][18][19]. Shown in Fig.…”

“…In multiple access systems different directions of transmission and reception can be used to communicate with different subscribers in order to increase the total throughput of the system [7][8][9]. A multipath radiation pattern for wideband and ultra-wideband PAA can be formed with both analog and digital methods [4,10,11]. In analog methods, as a rule, a feeder system, a set of phase shifters and summators on antenna ports are used.…”

The choice of elements for constructing a phased antenna array providing a relative frequency bandwidth up to 9% for the transmission or reception of wireless communication system information was made. Superposition of the excitation signals of a flat phased antenna array for a simultaneous emission of several independent beams in a radiation far field was used. Calculation and optimization of the progressive distribution of phase shifts in the excitation signal group in the horizontal and vertical directions of the phased array plane for the radiation (reception) of independent beams in spherical coordinates (azimuth and elevation) in space was performed. An experimental sample of the phased antenna array was developed using microstrip technology, which forms several beams in the radiation far field. An experimental measurement of the voltage standing wave ratio and relative frequency bandwidth of the sample developed by phased array microstrip and printing technology was carried out. The multi-beam phased antenna array will increase the number of subscribers for multi-user systems, as well as increase the energy efficiency for point-to-point communication by transmitting over multiple spatial trajectories.
