“…Difficulties to perfectly align the ridge gap circuit and the waveguide flange via an inline transition designed by means of steps, which significantly degraded the measurement results, motivated the need of identifying other transition alternatives. Thereby, we decided to investigate transitions from planar structures (coplanar waveguide [14] and microstrip [15]) to a ridge gap waveguide operating in F-band (90-140 GHz). The reason to choose this frequency band is that we have available "on wafer" probe stations operating up to 125 GHz, which allows us to test those transition designs.…”

Algaba-Brazález, A.; Flygare, J.; Yang, J.; Vassilev, V.; Baquero Escudero, M.; Kildal, P. (2016 Abstract-This paper describes the design and realization of a transition from a microstrip line to a ridge gap waveguide operating between 95 and 115 GHz. The study includes simulations, measurements, and a Monte Carlo analysis of the assembly tolerances. The purpose of this tolerance study is to identify the most critical misalignments that affect the circuit performance, and to provide guidelines about the assembly tolerance requirements for the proposed transition design.

“…Regarding to the SSGW to WR-15 transition, it is highlighted that the test-fixture of [859] presents the problem of having the rectangular waveguide extending vertically upwards from the top side of the PCB, whereas for antenna applications it is more convenient extend it downwards, as it is done in [787], for instance. The work improves a previous design [867] that uses a patch (as in or [856] or [857]), for the excitation of a rectangular waveguide. In the new design (see Fig.…”

“…The design is very basic, achieving RL > 10 in the GHz] band (RBW ≈ 20%), and it was used in the first GW designs. Three years later, Algaba [856] designs a transition between a CPW and a RGW through capacitive coupling with the aim of providing integration of active devices in RGW and facilitate measurements around f = 100 GHz. The transition consist in a CPW rectangular patch that couples to a RGW which has special end sections, adjacent to the ridge, in order to optimize the coupling.…”

“…The work is motivated by the poor performance of the coaxial solution of [855] at high frequencies. It is also highlighted that, despite of the fact that in [854] RGW to rectangular waveguide transitions are investigated up to f = 300 GHz, the alignment of the RGW and the flange by means of inline step transitions produces certain degradation, being more recommendable an approach closer to those of [856] or [857]. The adopted solution consists of a microstrip to RGW including a patch as it is done in [857].…”

“…The authors argue their motivation in that the coaxial to RGW transition of [855] provides a non-flat response from 12 GHz to 15.75 GHz and that the work in [856]- [858], although valuable, still presents some drawbacks. For instance, despite of the remarkable performance of the microstrip to RGW transition of [858] (sandwiched microstrip between ridge and upper plate), it results quite sensitive to accurate joining of the microstrip line to the center of the main ridge, and the packaging for such transition is foreseen as challenging.…”

The design of a resonant slot array antenna in a single layer ridge gap waveguide is presented. Linear and planar array configurations are developed. The linear array includes eight series slots in the ridge gap waveguide that is powered by a coaxial transmission line. The planar antenna array is developed by incorporating a power divider of four branches in the ridge gap waveguide layer. Each branch of the power divider feeds the linear array. The planar antenna detail design for Ku‐band is provided, and the manufactured antenna is measured. The antenna impedance bandwidth of 7% at 13.5 GHz centre frequency, the gain of 20.5 dBi and the side lobe level of <14 dB are obtained.
