Design and analysis of slotted waveguide antenna arrays

  • How does a slotted waveguide work?

    The principle of operation of a slot-waveguide is based on the discontinuity of the electric field (E-field) at high-refractive-index-contrast interfaces..

  • How to design slotted waveguide antenna?

    In the design, slot characterization is done with HFSS and by measurements, and mutual coupling between slots are calculated analytically.
    A MATLAB code is developed for the synthesis of the SWGA antenna..

  • What is slotted waveguide antenna?

    Slot antennas are usually used at UHF and microwave frequencies at which wavelengths are small enough that the plate and slot are conveniently small.
    At these frequencies, the radio waves are often conducted by a waveguide, and the antenna consists of slots in the waveguide; this is called a slotted waveguide antenna..

  • A slot antenna consists of a metal surface, usually a flat plate, with one or more holes or slots cut out.
    When the plate is driven as an antenna by an applied radio frequency current, the slot radiates electromagnetic waves in a way similar to a dipole antenna.
  • In a slot antenna, the current flows around the edges of the slot or aperture, resulting in a magnetic field that radiates the electromagnetic waves.
  • Slotted array antennas are typically manufactured from precision-machined aluminium components and dip brazed, resulting in a high-strength, lightweight assembly.
    Sylatech provides X, K and Ka Band slotted antenna arrays for Weather Radar, SAR, Fire Control and Surveillance Radar applications.
This paper illustrates the design and analysis of a multibeam metaposts loaded waveguide slotted antenna for 5G and C-band applications. The proposed antenna
