Design and experimental verification of ridge gap waveguide in bed of nails for parallel-plate mode suppression (2011, methodology): “The gap waveguide has many similarities with the so-called inverted microstrip line [23], and the rectangular ridge waveguide [24], as already pointed out in [1].”
Wide-Band Slot Antenna Arrays With Single-Layer Corporate-Feed Network in Ridge Gap Waveguide Technology (2014, methodology): “We have done a tradeoff and expect some leakage to neighboring elements but this leaked energy will be as low as 20 dB after one row of pins [13] and is acceptable for many antenna designs.”
Three metamaterial-based gap waveguides between parallel metal plates for mm/submm waves (2009, methodology): “This is achieved by using a single ridge surrounded by a high impedance surface [ 12 ], rather than other grooves and ridges like in the longitudinally corrugated hard surface.”
Narrow-Band Microwave Filter Using High-Q Groove Gap Waveguide Resonators With Manufacturing Flexibility and No Sidewalls (2012, methodology): “The articles [5]–[9] treat the ridge gap waveguide, but the gap waveguide technology can also be used to realize groove gap waveguides and microstrip gap waveguides [10].”
Parallel Plate Cavity Mode Suppression in Microstrip Circuit Packages Using a Lid of Nails (2010, methodology): “The bed of nails or pin surface was previously shown to have high surface impedance over a large bandwidth [2], and it was already proven in [1] to work in a ridge-type gap waveguide.”
Design Guidelines for Gap Waveguide Technology Based on Glide-Symmetric Holey Structures (2017, background): “The interest about gap waveguide technology has rapidly raised since its definition in 2009 [1] and the first experimental demonstration in 2011 [2].”
Design and Fabrication of a High-Gain 60-GHz Corrugated Slot Antenna Array With Ridge Gap Waveguide Distribution Layer (2016, background): “The gap waveguide technology introduced in [25-28] overcomes the problem of good electrical contact associated with mechanical assembly, by making use of a texture in one of surfaces that creates a magnetic wall (parallel-plate cut-off).”
Cost-Effective Gap Waveguide Technology Based on Glide-Symmetric Holey EBG Structures (2018, methodology): “As an alternative to SIW, gap waveguide technology was proposed in 2009 [2], [6].”
2$\times$ 2-Slot Element for 60-GHz Planar Array Antenna Realized on Two Doubled-Sided PCBs Using SIW Cavity and EBG-Type Soft Surface fed by Microstrip-Ridge Gap Waveguide (2014, methodology): “The gap waveguide technology was introduced in 2009 as an alternative to hollow waveguides and microstrip lines at high frequencies with performance close to rectangular waveguides if the dimensions are properly chosen [6], [7].”
