Design of filters based on gap waveguides

Passive RF and microwave components

In the communication systems for satellites, microwave filters play an important role [1]. Rectangular waveguide (RW) technology has been widely used to implement high-performance filters at microwave / mm-wave applications, owing to its high-quality factor, low loss, and high-power handling capability with respect to their substrate integrated waveguide (SIW) and planar counterparts [2,3]. However, SIW and planar filters offer a low profile, a reduced size, lightweight and an easy integration of components compared to RW filters. In addition, SIW and planar filters are cheaper to manufacture from printed circuit technology than RW ones using high-accuracy computer numerical control (CNC) machining. However, the high insertion losses of SIW and planar filters, due to the dielectric substrate and conductors, are their main drawbacks compared to RW counterparts.

Recently, gap waveguide (GW) technology has been developed to improve the longitudinal wave propagation between two air-filled parallel metallic plates [4]. The mains advantage of this technology is that it does not require metallic contact between both parallel plates, thus allowing the fabrication of low-cost components at millimeter and submillimeter wavelengths. The aim of this project is to analyze, design and implement filters in GW technology.
