We present an air-kernel network processing method using Gaussian kernels as base functions. The method first determines the cluster data using a functionally modified greedy sparse approximationmatrices. The algorithm then performs model reduction to try to reduce the final size of the beamformer. The method is being tested with simulations consisting mainly of two printed rough dipole gratings at two and seven half-wavelengths, in scenarios with 4 and 5 users from different elements. Antenna parameters typical of all DOAs are modeled, including the emitting dipole pattern and new spectrum coupling effects. This method is compared with various prior art non-linear processing methods to show near-optimal performance of the presented algorithm at a very affordable computational cost.

… The design specifications for the element in question are calculated using standardth equations, more fully these sizes can be used for the purpose of designing an array with a maximum degree of spacing between elements to improve general access to the array [10,11]. All simulation results of this device can be found in Figures 1 and 2. 3, 5 4, then 6. …
The proposed study, its task, is the design of a reasonable dual-band planar steerable beam antenna array of 4 elements using a feeder array. Variety of control dar.Beam implemented with two different proposals for S band adaptive antenna applications. A detailed design procedure has been developed, and for the main plan, a prototype must be built and tested, including diversity and antenna array feeding scheme. The network is capable of generating 4 beams in different paths depending on the applied input, which can reach the port of the hybrid directional coupler. The scanning range covered by this particular grating is wide: from -45° to +10° in the E plane and from -25 up to +25° in the H plane. The distance between the elements is optimized and is D1 = 86 mm and D2. = 40 mm to get the highest possible directivity, which can be 12.6 dBi at 3.6 GHz and 9.29 dBi at 2.4 GHz. Return loss considered is 40-76 dB at 3.6 GHz and -24.58 dB at 2.4 GHz. The integrated planar power supply is designed with Wilkinson power dividers and a directional hybrid coupler. If the main link in the network operates at 3.6 GHz, beam steering will be in favorable directions, and if it operates at 2.4 GHz, beam steering will be selected in the negative direction for the E-plane. Beam switching, based on the ideas applied to coupler port control, will occur in the H-plane for both frequency bands.
… However, this method is only effective when the signal is in -Noise Relation (SNR) is small, the network size is also small. In addition, in order to solve such problems,the class of recommendations for learning by examples [3,9,11] is false. However, their computational complexity can be high. …
This paper develops an ideal two-dimensional (2-D) direction estimation (DOA) algorithm for closely spaced L-shaped array sources. In the proposed algorithm, we formulate two or three ad hoc matrices depending on their antenna output covariance matrix using matrix multiplication, non-zero eigenvalues, and additionally corresponding eigenvectors constructed using the respective pair and DOA landmarks, respectively. The pairwise matching method is inconsistent when dealing with non-zero common eigenvalues of two spatial matrices, but theoretical analysis shows that this particular pairwise matching method does not result in a particular pairwise matching error. The DOAs of most sources are estimated using these eigenvectors, which correspond to non-zero eigenvectors, and subsequently using these eigenvectors.c sharply increases the accuracy of the DOA estimate. We also give a reason why the described method can distinguish related websites. The simulation confirms the overall performance of the proposed algorithm.
This background work features a different microwave component design developed for the suggested lighting control panel. In order to realize beam steering, two different schemes are proposed, namely the hybrid use of a beam steering network with a directional coupler and a beam steering network with switchable linear phase shifters to improve characteristics such as directivity, side-lobe level, beam width, etc. The number of maximum directions and throughput. These planar microwave components are designed for 5G S-band applications. Based on the required simulation results, a planning procedure was developed for a single-element E-shaped slot antenna, Wilkinson power divider, hybrid directional coupler. ya, the phase shifter of the loaded line and the switched phase of the line. shifter 3 around 6.0 GHz is obtained in detail. To create a beam steering array I would say use a slot antenna with a feed and a quarter wave transformer for impedance matching. Compared to conventional patch, slot antennas, the parameters have been improved, return loss (S11) is 26.32 dB, SWR 1.08 and directivity 7.6 dBi at 3.6 GHz and 7.39 dBi at 2.4 GHz. Hybrid directional coupler parameters: S11 – 20 – 0.83 dB, S21 – 3.39 dB, S31 – 3.56 dB, S41 and often 23.78 dB. Wilkinson divider power parameters: S11 must be ≤ 28.65 dB, S21 ≤ 3.46 dB and S31 ≤ 3 ≤ 3 is 0.46 dB. Loading and linear phase shifters with PIN diodes (MA4SPS402) are required to apply the phase shift to the array elements. For a loaded linear phase shifter, state S21 with a phase shifter was always ≤ 53.03°, and without a phase shifter ≈ 23.72°.
