“…This is because the waves can propagate as T E 10 modes if the width is more than λ/2. Hence if transition with larger substrate width is required, additional pins from the top metal plate above the substrate will be needed to suppress the unwanted modes in the substrate [12], [13]. In this proposed design the width of the PCB is (w s = 1.49 mm) less than Frequency (GHz) Fig.…”

In this paper a new microstrip line to groove gap waveguide transition has been proposed. The transition is based on a backshort cavity, which efficiently helps to couple the field from microstrip line to groove gap waveguide. In this transition the microstrip section lies inside the groove gap waveguide. Such contactless transition inside the waveguide is advantageous as it will allow easy packaging and integration of millimeter wave circuitry with gap waveguide components such as filters and array antennas. Alumina (r = 9.9) was used as the microstrip substrate for the proposed transition in this work. Measured results for the V-band transition show a relative bandwidth of 26% for a return loss better than 10 dB. The maximum insertion loss of the manufactured back-to-back prototype is found to be 1.32 dB, which also includes the losses of a 5.45 mm long microstrip line on an Alumina substrate. After subtracting the losses in the microstrip section, the losses in a single transition is found to be varying between 0.145 and 0.38 dB.

“…At high frequencies, due to small wavelength and dimensions, fabrication tolerances and good electrical contact requirements, the fabrication process of conventional waveguide components is a challenge. Gap waveguide technology is a newly developed technology based on soft and hard surfaces which has been used in many conventional microwave components . This technology overcomes the problem of good electrical contact associated with mechanical assembly especially at high frequencies.…”

In this letter, a groove gap waveguide (GGW) based 3‐dB directional coupler is proposed. The designed component is composed of three parts: GGW structure, extra matching pins and GGW to standard SMA transition. The designed quadrature 3‐dB coupler is optimized to work in the Ku‐band covering 13–15 GHz. Measured results show that over 14.3% bandwidth, 20 dB isolation and 1.2 VSWR is achieved. The main advantage of GGW‐based components is that it does not require good electrical contact among different metallic parts of the structure which considerably simplifies the manufacturing processes and hence reduces cost especially for millimeter‐waves applications.

“…This simplifies the mechanical assembly of the designed antennas and hence reduces the production cost for the antennas. Also, the gap technology can be used for RF packaging which makes it possible to integrate the RF electronics with the gap waveguide antennas [12][13].…”

Abstract-This paper deals with the design of patch antenna arrays with Ridge Gap Waveguides (RGW) feed networks at 60-GHz band. An array of 64 radiating elements are designed and simulated to demonstrate the good performance of the proposed array. The proposed antenna shows the gain up to 22.6 dBi, efficiency higher than 80% and an impedance bandwidth of 13% covering 59-67 GHz. The results are valuable for the design and evaluation of wideband planar antenna arrays at millimeterwave frequencies.Index Terms-patch antenna array, gap waveguide technology, 60 GHz applications.
