A Half-Mode Groove Gap Waveguide for Single-Layer Antennas in the Millimeter-Wave Band

Ferrando-Rocher, Miguel; Herranz Herruzo, José Ignacio; Valero-Nogueira, Alejandro; Baquero Escudero, Mariano (Institute of Electrical and Electronics Engineers, 2022-12)

[EN] This letter presents an alternative to significantly reduce the time and difficulty in designing and fabricating antennas in gap waveguide (GW) technology by using a novel half-mode groove GW. GW is often criticized ...
Design and experimental verification of ridge gap waveguide in bed of nails for parallel-plate mode suppression

Kildal, Per-Simon; Zaman, Ashraf Uz; Rajo Iglesias, Eva; Alfonso Alós, Esperanza; Valero-Nogueira, Alejandro (Institution of Engineering and Technology (IET), 2011-02)

This study describes the design and experimental verification of the ridge gap waveguide, appearing in the gap between parallel metal plates. One of the plates has a texture in the form of a wave-guiding metal ridge ...
Gap Waveguides using a suspended stripon a bed of nails

Valero-Nogueira, Alejandro; Baquero Escudero, Mariano; Herranz Herruzo, José Ignacio; Doménech Navarro, Javier; Alfonso Alós, Esperanza; Vila Jiménez, Antonio (Institute of Electrical and Electronics Engineers (IEEE), 2011)

This letter discusses the feasibility of a new type of waveguide consisting of a strip suspended on a bed of nails. The bed of nails enforces a stopband, while the strip opens a propagating path that can be used to design ...
High-Efficiency Ka-Band Circularly Polarized Radial-Line Slot Array Antenna on a Bed of Nails

Herranz Herruzo, José Ignacio; Valero-Nogueira, Alejandro; Ferrando-Rocher, Miguel; Bernardo-Clemente, Bernardo (Institute of Electrical and Electronics Engineers, 2022-05)

[EN] Radial-line slot-array antennas (RLSAs) provide an extremely simple solution to achieve high-gain circularly polarized radiation patterns without the need for complicated feeding networks or polarizers. The dielectric-filled ...
High-gain receive flat panel antenna for SATCOM in the move in K band

Pla Herliczka, Damián (Universitat Politècnica de València, 2022-10-14)

[ES] Hoy en día, implementar componentes pasivos a altas frecuencias y asegurar un apropiado contacto metálico y alineamiento entre sus piezas es un gran desafío. Las guías de onda son la solución más común y obviar el ...
Low-Sidelobe Flat Panel Array Fed by a 3D-Printed Half-Mode Gap Waveguide Amplitude-Tapering Network

Castellá-Montoro, Adrián; Ferrando-Rocher, Miguel; Herranz Herruzo, José Ignacio; Valero-Nogueira, Alejandro (Institute of Electrical and Electronics Engineers, 2024)

[EN] This article presents the design and evaluation of an 8 x 8 Ka-band low-sidelobe slot array antenna using gap waveguide technology. The slot array is fed by a single-layer amplitude-tapering network implemented in ...
