Slot waveguide modes

Omnidirectional Sector Waveguide SLOT Antenna
L and C Band (1296 & 2320 MHz)

The slotted waveguide has achieved most of its success when used in an omnidirectional role. It is the simplest way to get a real 10dB gain over 360 degrees of beamwidth.
The Slotted waveguide antenna is a Horizontally Polarized type antenna and light in weight.
3 Tuning screws are placed for tweaking the SWR and can be used to adjust the center frequency of your choice.
Each Slot antenna is supplied incl measurement plot from our RF network analyzer following your center frequency assignment.

A slot-waveguide is an optical waveguide that guides strongly confined light in a subwavelength-scale low refractive index region by total internal reflection. A slot-waveguide consists of two strips or slabs of high-refractive-index (n H) materials separated by a subwavelength-scale low-refractive-index (n S) slot region and surrounded by low-refractive-index (n C) cladding materials. Silicon slot waveguide Bragg gratings have been designed, fabricated and the experimental data has been analyzed for its slow light properties. Slow light with a group index of 12.38 at a.

  • Slot-waveguides allow light to be guided and strongly confined inside a nanometer-scale region of low refractive index. Thus stronger light-analyte interaction can be obtained as compared to that achievable by a conventional waveguide, in which the propagating beam is confined to the high-refractive-index core of the waveguide.
  • The slots on the waveguide will assumed to have a narrow width. Increasing the width increases the Bandwidth (recall that a fatter antenna often has an increased bandwidth); the expense of a larger width is a higher degree of cross-polarization.
  • One type of traditional waveguide slot array antenna utilizes narrow (in terms of wavelength) slots in the broad wall of the guide, as shown in Figure 1a. The high power-capable, large-slot array antenna concept is formed from a collection of large apertures in the broad wall of standard rectangular waveguide, as shown in Figure 1b.

The model analyses the mode propagation within a nano slot waveguide. In a slot waveguide configuration, two high refractive index slabs (~3.48) are placed adjacent to the low refractive index slot (~1.44). Mode analysis was performed on a 2D cross section of a slot waveguide for an operating wavelength of 1.55[um]. Further analysis was carried out to optimize the width of the slot to deliver maximum optical power and optical intensity through the slot area.
