Interdigital Band-Pass Filter with Half-Wave Resonators

New kind of interdigital filter is considered. Quarter-wave length resonators, which are usually used have been replaced by half-wave resonators. This solution permits to apply interdigital filters up K frequency band. Coupled structures excited in the centre of input resonators are described. Results of practical researches of interdigital band-pass filter with half-wave resonators in K band are presented.
