recently a new structure called groove gap waveguide (GGW) is ‎introduced to implement low loss microwave component devices ‎especially for millimeter wave applications. This paper presents a ‎new type of H-plane horn antenna making use of this new technology ‎in which backward radiation is significantly suppressed by ‎introducing a high impedance surface at the antenna aperture. The ‎high impe...

In this paper, two H-plane horn antennae are designed using groove and ridge gap waveguide (GGW RGW) techniques. the proposed structures, is partially filled with a dielectric to control amplitude phase distribution across antenna aperture so that very low side lobe level (SLL) can be achieved. Two sample simulated for frequency range from 12 16 GHz, prototypes fabricated. The fabricated show q...

A compact triple-layer series fed slot unit array using Groove Gap Waveguide (GGW) technology for 5G millimeter-wave applications is presented in this paper. The design employed a two-step coupling mechanism the radiating slots. aperture when combined with groove gapWaveguide allows achieving three different goals: First, reduction of size transversal direction, so more arrays can be added with...

In this letter, a half-mode waveguide based on gap (GW) technology for rapid prototyping is explored. Two devices have been designed and measured demonstration purposes: power divider curved waveguide. Both are constructed from two noncontacting metal pieces. also follow the same design process. bottom piece, horizontally polarized groove GW (GGW) housed. The height of about half, which require...

Abstract In this paper, a W-band 3D-printed bandpass filter is proposed. The use of higher-order TE 10 n modes in groove gap waveguide (GGW) technology evaluated order to alleviate the manufacturing requirements. addition modes, coupling between them analyzed detail improve overall fabrication robustness component. This allows implementation narrow-band filters operating at millimeter-wave freq...

In this paper the transmittance of metal-insulator-metal (MIM) waveguides containing semi-circular ring shaped and rectangular ring shaped grooves are investigated. By varying groove parameters their effects on the transmittance of the MIM waveguides are investigated. The results show that the transmittance spectra of the waveguides have maximum and minimum points, and by using appropriate para...

A coaxial-to-groove gap waveguide transition is proposed for the first time, addressing lack of similar designs in state-of-the-art literature. An in-line configuration adopted case stringent space requirements groove systems. This device has no dielectric and makes use a multi-step ridged section connected to inner conductor coaxial line. Three versions are presented, covering progressively wi...
