Ceramic‐elements‐based distributed resonators and filters

The aim of this paper is to introduce a new family low-profile resonators and filters that achieve high performance low insertion loss without the need for post-production tuning. resonator termed ceramic-element based distributed consists matrix subwavelength-length ceramic posts connected in inter-digital fashion top bottom ground planes. Such disposition elements beneficial two main reasons. First, frequency operation such becomes function its height, unlike case standard resonators. Second, element performs inherent dimensional averaging, resulting filter requires no As demonstrator proposed technology, two-pole using with dielectric permittivity 37 tangent 0.0033 operating at centre 3.5 GHz was designed, fabricated tested. measured predicted results are excellent agreement extensively discussed.
