Optimization of thermal regimes of microwave resonators digital active phased array antenna

Abstract

Objective. The aim of the study is to simulate resonators for microwave digital active phased antenna arrays (DFAAR) in the microwave range, which will optimize the parameters of the antenna system for more reliable direction finding with high reliability of any aircraft. Method. The use of one-sided surfaces in the Mobius shape as resonators makes it possible to implement a new type of microwave resonators in the form of an integrated capacitance and a two-turn inductance. The parameters of such a resonator make it possible to realize a traveling or standing wave, depending on the geometric dimensions. Result. The use of innovative resonators for microwave DFAAR with p-i-n diodes to change the area of the capacitor makes it possible to implement a two-frequency method of pulse-code modulation. On the basis of such resonators, it is possible to realize a standing wave at one position of the p-i-n diodes, and a traveling wave at the other. Such electromagnetic waves, transmitted by the DFAAR, can track objects in the stealth mode. Conclusion. The use of traditional resonators for DFAAR of the microwave range allows you to discretely adjust the parameters of these resonators by turning on / off p-i-n diodes with positive and negative voltages to control the frequency properties of the resonators and set the traveling or standing wave modes.
