摘要：
The question of increasing the tuning band of microstrip resonators that use ferroelectric capacitors for tuning in the region of increased electric lengths is considered which allows using them in the upper part of the centimeter band (Ku-band, K-band). Band properties of regular and step-irregular resonators operating at the lowest resonant frequency are analyzed. It is determined that step-irregular resonators possess a wider tuning band than regular ones. Their use allows widening the tuning band by 1.5 or more times. If the ferroelectric capacitor overlapping in capacity Cmax/C min = 2.2 then at frequencies 10 GHz and 20 GHz step resonators can provide 28% and 22% tuning band, respectively. © Allerton Press, Inc., 2010.
