Abstract :
A way is presented to realize attenuation poles in microstrip bandbass filters of symmetrical pairs of coupled lines. The pole locations can be controlled by the parameters of additional single microstrip lines or other impedances. Different types of coupled pairs must be used to realize attenuation poles below and above passband.
