This paper overviews the state-of-the-art of substrate integrated waveguide (SIW) techniques in the design and realization of innovative low-cost, low-profile and low-loss (L3) millimeter-wave antenna elements, feeding networks and arrays for various wireless applications. Novel classes of multilayered antenna structures and systems are proposed and studied to exploit the vertical dimension of ...

In this work, a novel electrically reconfigurable phase shifter based on half-mode substrate integrated waveguide (HM-SIW) is proposed. SIW guided transmission line topology, and by using excitation, smaller size can be achieved. Phase shifters are electronic devices that change the of for wide range applications, including inverse scattering sensing. The tunability PIN diodes applied here to a...

A single pole double throw (SPDT) discrete switch design using switchable substrate integrated waveguide (SIW) resonators is proposed in this paper. It was designed for the millimeter wave multiple input output (MIMO) transceiver. An example application 5G communication 26 GHz band. High isolation between transmitter and receiver (in transceiver) needed SPDT to minimize any high radio frequency...

A bandpass negative group delay (NGD) passive circuit based on defect ground structure (DGS) and substrate integrated waveguide (SIW)-matched is developed in the paper. The NGD DGS topology originally built with notched cells associated self-matched elements. design method introduced as a function of geometrical SIW via Then, parametric analyses full wave 3-D electromagnetic <tex xmlns:mml="htt...

This paper discusses for the first time the combined optoelectronic-electromagnetic modelling of a new technology that represents a paradigm shift in the way millimetre-wave and terahertz electronics can be implemented using the REconfigurable Terahertz INtegrated Architecture (RETINA) concept. Instead of having traditional metal-pipe rectangular waveguide structures with metal sidewalls, RETIN...

We demonstrate a silicon (Si)-gallium arsenide (GaAs) semiconductor-based holographic metasurface antenna operating at 94 GHz. The molds the radiated beam by resorting to approach involving modulation of guided-mode generated pillbox beamformer. beamformer is fed three integrated horns in substrate-integrated waveguide (SIW) technology located focal plane parabolic reflector correspond independ...
