Antenna array based on a substrate integrated waveguide for radars and communication systems operating within 18...42 GHz frequency band
The gain of a 16-channel printed high-potential antenna array is calculated on the basis of a substrate integrated waveguide in the frequency range of 18…42 GHz. The influence of inaccuracies in manufacturing the antenna array on the operating range of radar systems and communication systems is determined. The main reasons for the decrease in the antenna array gain in the upper part of the researched frequency range are determined.
