Microwave probe is designed which is useful measurement tool for inspection of AESA individual channels equipped with printed dipole radiating elements. The probe is placed over any one radiating element of flat array antenna, electrically screens the element thus removes mutual coupling in array, and provides radiator input's matching in 10%-width passband. Due to neighboring radiating elements have no influence on the measurement results, a combination of vector network analyzer and the probe can be used to diagnose individual vibrators and check their identity within the array, to measure TX/RX modules' amplitude and phase frequency responses "through the radiator" as well as modules' power output.

The paper presents the results of observation of the effects of refocusing on the line Moscow – Rostov, demonstrates the implementation of refocusing of the regular type in the ionospheric propagation of radio waves, not associated with the influence of traveling disturbance in the ionosphere. The possibility of nontrivial interpretation of mechanisms of ionospheric propagation of HF radio waves at reception of signals of exact time is analyzed.

A subarray for Ku-band wide-angle scanning antenna array based on waveguide continuous transverse stubs (CTS) is presented. The proposed antenna array consists of 2 subarrays, subarray consists of 16 horn radiators. The subarray based on waveguide continuous transverse stubs is fed by a waveguide binary power divider. The CTS subarray for scanning antenna array was calculated and researched. The developed subarray has compact structure, light weight, manufacturability and high efficiency. A beam-scanning range of ± 90° is achieved by mechanically rotating subarrays around its axes at the same angles. The calculated aperture efficiency exceeds 55% in the entire working frequency band. The proposed scanning antenna array with high efficiency can be used for satellite communication terminals and radar systems.

This paper discuss the improvement, proposed by a number of authors, of the performance in the low – frequency part of the sounding range, which is essential for the developed ionosondes with a decrease in the lower frequency of sounding. The ways to compensate for the decrease in the energy potential of the decameter sounding channel in satellite monitoring of the ionosphere from high-apogee orbits by increasing the efficiency of short-wave antennas of satellite ionosondes are considered.

In the frequency range 3.2-12 GHz the absorption of microwave energy was measured by new composite materials, which are xLSMO/yGeO2/(1-x-y)NaF (LiF) glass ceramics, where x, y are the mass fractions of the composite components, x =0.7-0.95 , y=0.05-0.20. Conductivity measurements were performed, structural and microstructural features of materials were studied. It has been found that concentrations of germanium oxide and fluorides significantly affect the degree of absorption of microwave energy by samples. Absorption spectra close to linear ones at levels from 0-3 dB to 12-14 dB were obtained in the whole investigated frequency range for various materials. Some increase in the absorption (5-10%) of energy by these composite materials under the influence of a weak (H≈300 kOe) constant magnetic field was revealed. The spectra of the integral radiation of the electric field were measured with the composites with the lowest conductivity. Prospective areas of work have been outlined for obtaining broadband radio-absorbing composite materials.

This article is devoted to the task of designing a radiating microwave module for a device for diagnosing bronchopulmonary diseases, based on the method of radiofrequency scanning of the chest. The main tasks of the radiating module are forming a probing microwave signal with specified parameters — frequency and power, minimizing side spectral components. However, in order to provide radio frequency scanning and further interpret the measurement results, the radiating module must be precisely positioned on the chest surface. A structural diagram of the radiating module, its practical implementation, as well as integration with the radiating antenna applicator and two versions of the positioning system are presented.

A phased study of the characteristics of the printed antipodal Vivaldi antenna models based on a substrate integrated waveguide in the frequency band 18-42 GHz was carried out. It was found that both the dimensions of the aperture and the exciting segment significantly affect the gain of the antennas as well as their matching in the frequency band. Antenna models were analyzed in CST Microwave Studio. Matching characteristics and radiation patterns are presented.
