The waveguide is loaded with a double-slot iris to perform an impedance match and to suppress undesired modes that can propagate on the cavity.
IEEE Xplore: IEEE Transactions on Antennas and Propagation - ( ) The first antenna based on substrate integrated gap waveguide (SIGW) is presented. Using two contacted metal strips to build the required conducting ridge, the SIGW addresses the defects inherent in the printed gap waveguide at millimeterwave frequencies.

Sensors and Actuators A: Physical, Vol. 224, Issue. , p. 163. Investigation and Design of a Slotted An example of a standing wave slotted waveguide antenna is given in [19], where a ridged waveguide is used to help extend the scanning an-gle of a frequency scanned antenna. This work done in [19] ties in very closely to what is done here, as the basic topology of the antenna is similar. Micromachined millimeter wave | 2.2.1.2 Membrane … A ridge waveguide is placed to feed the horn and the waveguide slot antennas at the end. Therefore, a transition from the rectangular coaxial line to a ridge waveguide is designed. Low loss transmission lines are used to produce the best possible system performance. I. Introduction | III. Slotted Waveguide Antenna Array Two architectures, based on slotted waveguides and microcoaxial line fed slots, are introduced to provide a wider scanning angle than conventionalFigure 4 (a) shows a waveguide slotted array with 10 slots. In this case longitudinal slots are used. In order to achieve the greatest possible scan...
Design and simulation results of the linear array show that it is possible to have a slot array antenna with 20 % bandwidth based on ridge gap waveguide technology. View Show abstract
Recently, ridge gap waveguides are considered as guiding structures in high-frequency applications. One of the major problems facing this guiding structure is the limited ability of using all the possible bandwidths due to the limited bandwidth of the transition to the coaxial lines. Here, a review of the different excitation techniques associated with this guiding structure is presented. Long Slots Array Antenna Based on Ridge Gap Waveguide ...

A mmWave Wideband Slot Array Antenna Based on Ridge Gap Dec 11, 2017 · Abstract: A wideband 8 × 8 element slot antenna array based on ridge gap waveguide feeding network has been proposed for mmWave applications. The antenna subarray consists of four radiating slots which are excited by a groove gap cavity layer. Compared with previously published works, the proposed planar antenna array has quite wide impedance bandwidth. Slot antenna in ridge gap waveguide technology
Without any air gap, the antenna provides wideband but, the gain is very poor. For the other three different values of h a, the S 11 plots are showing a similar kind of nature but it changes quickly due to the combine effect of the change in dielectric constant, antenna dimension, waveguide dimension, and vias height. So, the introduction of ... Flat Plate Slotted Waveguide Array Antennas - Cobham plc waveguide assemblies since 1977, has been manufacturing flat plate / slotted waveguide array antennas since the acquisition of Litton Airtron’s microwave products group in 2001. Litton Airtron began manufacturing antennas in 1960 and quickly became the recognized leader in the design and development of commercial and military arrays.The legacy
