Effects of electromagnetic interaction in microwave multipleplaced planar structures and development of the theory of filters for telecommunication system

A theory has been developed for multi-tiered bandpass filters of a planar structure, its position is confirmed by measurements on existing experimental samples. On the basis of the established theoretical positions, new circuit design solutions for bandpass filters with different frequency characteristics have been created, which is reflected in the patent materials. It is established that three- resonator filters with a mixed cross-coupling K 13 = K m + K e , equal to zero (К 13 = 0), have two equidistantly located damping poles or a constant delay time.
