Abstract :
A new helical-filter structure is proposed, having as its model the generalised interdigital microwave network. The structure consists of two rows of resonators, with crosscoupling between rows. This configuration, which can be implemented at low cost, can realise a wide variety of responses. A design example of a linear phase filter is given.
