摘要：A description is given of a high frequency filter comprising microstrips. The filtercomprises at least two resonators (16, 18) which each have, as frequency-determiningelements, a first straight microstrip section (28) and a second straight microstrip section(30), which are parallel next to each other, and also a capacitor assembly (22). In eachresonator the capacitor assembly is connected between first ends of the microstripsections and each resonator is exclusively connected to ground at the second ends of themicrostrip sections. In each resonator (16, 18) the sum of the two microstrip sections actsas inductive lement. The resonators (16, 18) therefore act in the same manner as aresonator having a single microstrip, the length of which corresponds essentially to thesum of the lengths of the first microstrip section (28) and the second microstrip section(30). This construction of a filter allows a shorter design compared to conventional filterstructures.
