TY - JOUR A1 - Martínez Mendoza, Mónica AU - Gómez Díaz, Juan Sebastián AU - Cañete Rebenaque, David AU - Álvarez Melcón , Alejandro T1 - Design of Dual-Bandpass Hybrid Waveguide-Microstrip Microwave Filters Y1 - 2008 UR - http://hdl.handle.net/10317/1672 AB - A simple dual-bandpass filtering structure is pro- posed. The filter is implemented by means of a new hybrid waveguide­microstrip technology. The novelty of the structure is that it combines two standard printed microstrip coupled line resonators, with a resonance of the base waveguide cavity, to implement a dual-band operation. Important aspects about the filter design, useful for practical applications are treated. This includes a study on the maximum coupling that can be achieved to the cavity resonance, and guidelines to control the positions of the two passbands and the transmission zeros. Besides, an example has been designed, manufactured and tested. The measurements on the fabricated prototype have confirmed the validity of the new structure to perform dual-band operation.
