COMPACT BAND PASS FILTER
First Claim
Patent Images
1. A compact band pass filter (BPF), comprising:
- a first transmission line electromagnetically coupled to a second transmission line; and
an isolating surface positioned between the first transmission line and the second transmission line, wherein the isolating surface includes at least one aperture designed to produce a desired electromagnetic coupling between the first transmission line and the second transmission line wherein the coupling produces a passband such that certain frequencies within an input transmission signal are filtered out.
