Miniaturized micromachined dual mode cross slot 5 pole filter

This paper presents a new planar miniaturized micromachined 5 pole bandpass dual-mode cross-slot filter at 19.82 GHz. A 5 pole filter is presented with 2 dB of insertion losses with a fractional bandwidth of 400 MHz and a high rejection (40 dB) at 19.1 GHz. A thermal study was also achieved to ensure the structure is ready for space conditions.
