Q factor and insertion loss analysis of half-height pin ridge gap waveguide

Paper in proceeding, 2016

The promising millimeter wave transmission structure, gap waveguide, has advantageous characteristic compared to conventional ones. As for the ridge gap waveguide (RGW) and groove gap waveguide (GGW), they usually can be fabricated by milling technology, the height and the gap between the pins always are the main factors for the cost. Recently, half-height pin, a new pin form, is proposed for the gap waveguide technology to effectively reduce the manufacture cost and difficulty. In this paper, the Q values and insertion loss of the RGW using half-height pins will be investigated carefully in terms of the structure of the ridge and pins.
