Abstract :
A V-band bandpass filter has been fabricated using integrated rectangular-coaxial lines. The use of integrated coaxial lines allows the fabrication of a compact filter measuring 6.5×2.0×0.1 mm. In addition, the coaxial lines isolate the filter from the external environment, allowing filters to be spaced close to other devices without electromagnetic coupling. The fabricated filter has a center frequency of 57.5 GHz and a bandwidth of 2.5 GHz. The measured insertion loss is 18.5 dB. This integrated coaxial technology can provide low-loss, nondispersive, non-radiating components, well suited to applications in antenna beamforming.
