Long slot array antenna based on ridge gap waveguide technology
A Large Frequency Interval Dual-band High-gain Slot Array ...
In particular, phased array technology allows the radar beam to be controlled and adapted almost instantaneously. This flexibility enables the radar to carryPhase shifters are widely employed in radar systems based on phased antenna arrays. MEMS technology offers much lower insertion loss... Hard waveguides based on gap waveguide concept A new geometry based on the concept of gap waveguide has been proposed to allow the propagation ofBesides, the design has the advantage of gap waveguides of being a contact-less technology. The results can be seen as well as the horizontally-polarized version of the ridge gap waveguide. Microwaves101 | Double-Ridged Waveguide Single ridge waveguide can be thought of as half of a double ridge waveguide with a horizontal perfect electrical conductor (PEC) inserted at exactly the middle of the gap region. This waveguide will have the same cut-off frequency of the fundamental waveguide mode, however the higher order...
Long Slots Array Antenna Based on Ridge Gap Waveguide Technology Abstract: Ridge gap waveguide (RGW) technology is used in the design of a frequency scanning antenna with high gain and directivity. A Quasi-TEM horn with shaped ridge is designed as a guiding structure between two metallic surfaces. The waves are suppressed beyond the shaped ...

Ku band linear slot-array in ridge gapwaveguide technology Abstract. A Ku band 4×1 linear slot array antenna design based on recently developed gap waveguide technology is presented. The complete antenna has been built using two parallel plates where the bottom metal plate has the guiding ridge and periodic pins and the top metal plate is smooth. Solving Microwave Challenges with Low-Loss Gap Waveguide ... Gap waveguide can provide 77 GHz radar in a lower cost and more c Figure 3. Designed for millimeter 5G applications, millimeter wave, is a phased array antenna with 65dBm EIRP at 28 GHz based on gap waveguide technology. Source: Gapwaves AB ompact form for easier integration into the vehicle. Millimeter-wave Substrate Integrated Printed Ridge Gap ... wave antenna based on a periodic structure and connecting the antenna to the standard 50 Ω equipment. For achieving this purpose a quasi-TEM transition and a transition from microstrip to substrate integrated ridge gap waveguide has been designed. In addition, the slots of the

Rotman lens with Ridge Gap Waveguide technology for ... In this paper, a Rotman lens with Ridge Gap Waveguide technology (RGW) is proposed as an alternative for beam scanning in millimeter wave applications. To facilitate the design and measurements, a first prototype at 38 GHz will be designed and built; afterwards a final device at 60 GHz will be designed. Design of Slotted Waveguide Array Antenna Fed by H-Plane ...
