In this research a novel design of monopole microstrip antenna is introduced. The proposed antenna has a compact size of 2.1 × 1.5 × 3.175 cm3 with a simple structure consisting of semi-triangular patch shape with a coplanar waveguide (CPW) feed line. The antenna provides a wide bandwidth covering frequencies from 4. 5 GHz to 15 GHz with an input reflection coefficient (S11) smaller than –10 dB over the entire range. The obtained percentage bandwidth is 107% at the center frequency 9.8 GHz. The radiation pattern of the antenna is directional in E plane with realized gain 5.3 dB. This property makes the proposed antenna suitable for many crucial applications including medical, radar and satellite applications.

A high-performance spectral analysis method for broadband signals is presented, which is based on the theory of digital signal processing. According to the proposed method, the partition of a broadband signal selection array is performed on a number of sub sequences. The formed subsequences are processed in accordance with the Fourier Fast Transform (FFT) algorithm. In the framework of the proposed method, expressions were obtained for calculating the main parameters of FFT structure.The analysis of the efficiency of the proposed method has proved that the productivity of the digital spectral analysis of broadband signals increases in 1,2 ÷ 4,7 times, depending on the length of the processed subsequence and the volume of the analyzed sample of the signal.

The algorithm for estimating the motion parameters of unmanned aerial vehicles as elements of flying wireless sensor networks FANET is considered. To estimate the motion parameters, the proposed stable dynamic filtering algorithm allows us to obtain estimates of coordinates and their derivatives. The results obtained can simultaneously improve the accuracy of the estimation of motion parameters, ensure the sustainability of the assessment process and the efficiency of managing the elements of the wireless sensor network FANET.

In the given paper, we discuss the lattice-based open source public-key NTRU cryptosystem that can be used in IoT (Internet of Things). IoT spans users' personal sensitive information and many crucial aspects of person's private life and therefore IoT requires a special protection. IoT security involves the network security and the devices security they are connected to. Cryptography technologies are the best solution to withstand communication attacks. NTRU can implement the NTRUEncrypt public key encryption algorithm capable of withstanding the attacks from the quantum computers. Therefore, NTRU is significantly faster than the other public-key cryptosystems such as RSA or ECC, allowing long-term cryptanalysis. NTRU can use one-off keys making possible to change keys in a few seconds what makes difficult for an attacker to crack the encryption trying to obtain more than thousands of keys for doing that.

The paper represents stress assessment of electronic packages with complete compound encapsulation subjected to thermal impacts. The stress calculation scheme for the joint of electronic component and surrounding layer of compound is brought to axially symmetric problem of two joined thick-walled cylinders and described by using Lame-Gadolin theory. The mathematical model was obtained by solving statically indeterminate problem. Formulas for radial and tangential stress and contact pressure calculation were obtained for stationary thermal condition. Non-stationary problem of thermal conduction in the sealed package was solved. The problem of non-stationary radial distribution of temperature in electronic component and compound was solved. Calculation formulas were optimized for the ultimate thermal impact on the encapsulated package.

a high-precision numerical adaptive method of integration of the systems of linear differential equations with time-varying coefficients is presented in the paper. The adaptability of the method lies in the fact that at each step of the integration, threre is the refinement of the result which is accomplished by adding to it a certain number of refinement terms from a Taylor series for the searched functions. The number of these terms, according to the curvature, is different, which determines the adaptability of the method. Some examples were provided.

The paper proposes a mathematical model of queue management on routers interfaces of telecommunication networks. The novelty of this model is the approach to a consistent and coordinate solution of such interface tasks as Congestion Management, Resource Allocation and Congestion Avoidance. These tasks were solved in the course of the optimization problem of quadratic programming.
