Review on Optical Waveguides | IntechOpen

Slot antennas in waveguides provide an economical way of the design of antenna arrays.In practice, these slots are all covered with a thin insulating material (for the protection of the interior) of the waveguide. This material may not be hygroscopic and must be protected from weather conditions.

Polarization Agility in Annular Waveguide Slot Antenna (AWSA ... Ability of annular waveguide slot antenna (AWSA) arrays to radiate arbitrary linear horizontal or vertical polarization is presented in this paper for the first time. By forming a 4-element AWSA array and choosing the proper feed coefficients, linear polarization in any of the two principal directions is achieved.
