Description

The utility model relates to the field of radio engineering, in particular to antenna devices, namely to phased array antennas for wireless communication systems, and can be used in millimeter-wave radio systems.

Known digital ring antenna array (patent RU2630846, H01Q21 / 00, 06.16.2016), made in the form of a round shape, where the printed antenna emitters are installed, on the front side of the base are printed antenna radiators (type of antenna - Vivaldi) connected by high-frequency connectors to digital transceiver modules located on the opposite side of the base, power system modules, functional control and information processing modules, a signal synthesizer module and a frequency splitter.

The disadvantage of the analogue is limited functionality due to the fact that the device does not generate radio signals with a given spin-orbit state.

Known broadband waveguide slotted two-channel emitting device of circular polarization (patent RU 2386199, N 01Q13 / 00, 11.01.2009), consisting of a segment of a rectangular waveguide with two short-circuit plugs in end sections, with a resonant cross-shaped slit on a wide square-shaped front wall.

The disadvantage of the analogue is the limited functionality due to the fact that the device does not allow you to set the order of the spin-orbit moment of the emitted radio signals.

Closest to the proposed utility model is an antenna fragment of a phased antenna array with controlled polarization (patent RU92745, H01Q21 / 26, 30.11.2009), which is a linear array containing N turnstile printed emitters, each of which consists of two orthogonally combined into a three-dimensional structure symmetrical printed vibrators located with a certain period in a row above a common conductive screen at a height equal to a quarter of the average wavelength of the working range, with each printed vibrato p is made on a dielectric substrate according to the classical upper supply circuit and contains strip conductors forming the vibrator arms structurally combined with a balancing device and a supply strip line, the lower end of which is connected to a coaxial-strip transition, moreover, the balancing and excitation of each vibrator included in the antenna the fragment is carried out by three connected strip conductors of length λav / 4, two of which, the middle and left extreme, form a slot waveguide, the upper ends of which connected to the shoulders of the vibrator, and the lower ones are short-circuited, and the third extreme right conductor, which is a feeding connected line and having a tuning element made in the form of a step, is connected to the RF connector on the dielectric substrate (circuit board) with the lower end and the upper end with the shoulder of the vibrator, which is connected to the left extreme stripe conductor.

The disadvantage of the prototype is limited functionality, consisting in the fact that the emitters located in a rectangular plane do not allow the formation of a radio signal with a given spin-orbit state.

The objective of the utility model is to increase the information security of radio channels due to the fact that the transmission of radio signals in each channel is carried out using radio emission with a unique predetermined spin-orbit state.

The technical result is the formation of radio signals with a given spin-orbit state.

The problem is solved, and the technical result is achieved by the fact that in the antenna array consisting of N printed emitters, according to the utility model, the printed emitters are made circular and arranged around a circle of radius 2λ at a distance λ between the centers of adjacent printed emitters.

The essence of the utility model is illustrated by drawings. In FIG. 1 shows 8 printed radiators of an antenna array located around a circle of radius 2λ, with supply conductors (front view). In FIG. 2 shows the ground plane (rear view). In FIG. 3 is a side view of an entire structure consisting of printed emitters, a dielectric substrate, and a ground plane.

The antenna array for generating radio signals with a given spin-orbit state includes (Fig. 1) circular printing emitters 1 (Fig. 1, Fig. 3) located around a circle of radius 2λ at a distance λ between the centers of adjacent printed emitters, the associated supply conductors 2 (Fig. 1) connected to the input port 3 (Fig. 1) located on the dielectric substrate 4 (Fig. 1, Fig. 3). The plane of the earth 5 (Fig. 2, Fig. 3) is located on the reverse side of the dielectric substrate 4 (Fig. 1, Fig. 3).

Circular printed emitters 1 and supply conductors 2 are deposited on a dielectric substrate 4. A terminal lead of a 1.0 mm connector is connected to an input port 3, and an external terminal of a 1.0 mm connector is connected to the ground plane 5.

The entire structure of the antenna array is made according to the technology of manufacturing printed circuit boards and is designed to operate in the frequency band 77-78.5 GHz. Input port 3 is rated for 50 ohms.

The antenna array for generating radio signals with a given spin-orbit state works as follows: an electric signal is supplied to the input port 3 (Fig. 1), propagates along the supply conductors 2 (Fig. 1) and reaches the circular printing emitters 1 (Fig. 1, Fig. 3), where the electric current is converted into the energy of the electromagnetic field created between the plane of the earth 5 (Fig. 2, Fig. 3) and the printed emitters 1 (Fig. 1, Fig. 3). The dielectric substrate 4 (Fig. 1, Fig. 3) shields the printed emitters 1 (Fig. 1, Fig. 3) and the ground plane 5 (Fig. 2, Fig. 3) from each other and ensures structural stability.

Since the lengths of the supply conductors 2 (Fig. 1) are different, the electrical signals supplied to 8 circular printing emitters 1 (Fig. 1, Fig. 3) will have different phases (specifically, there is an increase in phase by π / 4 for each subsequent printing emitter when moving clockwise), thus setting the order of the generated spin-orbit state of the emitted field. By combining the oscillations from all circular printing emitters 1 (Fig. 1, Fig. 3), the electrical signals to which are delivered with phase shifts, the resulting radiated field with a given spin-orbit state is formed.

So, the claimed utility model allows you to generate radio signals with a given spin-orbit state and increases the information security of radio channels due to the fact that the transmission of radio signals in each channel is carried out using radio emission with a unique predetermined spin-orbit state.
