The problem of reducing the side-lobe level of the radiation pattern of the trough waveguide antenna has been considered. To solve this problem, weighting the height of the elements of excitation has been used. For increasing the efficiency of the weighting, it is proposed to use a weight function that takes into account the losses of the exciting wave as it passes through the elements of the exciting...
The advantages of the application of coupled biconical resonators for measurement of coaxial metal-dielectric structure in microwave range are demonstrated. The particularity of the approach is the use of one of coupled resonators as reference one and another for placing specimen that provides possibility to measure difference between corresponding resonance frequencies and the ratio of frequency...
The analysis of the natural frequency and estimation of Q-factor of the open resonator by means of fractional-rational approximation of the reflection response has been considered. An advantage of the proposed technique in comparison with the classical methods has been demonstrated. Dependence of Q-factor of the shielded half-disk dielectric resonator and estimations of the poles and the zeros of...
Estimation of Q-factor of the open resonator by means of fractional-rational approximation of the reflection response has been considered. An advantage of the proposed technique in comparison with classical methods has been demonstrated. Dependence of Q-factor of the half-disk dielectric resonator and estimations of poles and zeros of resonance response against coupling coefficient value has been...
