Abstract:
|
This paper presents the design and implementation
of multimodal uniplanar bandpass filters which use loaded
coplanar-waveguide-slotline tees in the slotline resonators to
reduce the filter length. The tees are theoretically analyzed to
obtain a multimodal model, and applied to the design of two
second-order bandpass filters at 1.5 GHz, one with reduced
length and the second with compact dimensions (0.16¿ × 0.069¿).
The filter measurements validate the theory, exhibiting an
insertion loss of 1.55 dB (reduced-length filter) and 2.6 dB
(compact filter) with a 8% bandwidth. |
