A radial-line slot antenna (RLSA) is a high-efficiency planar array. A double-layered radial line and uniform slot length have been adopted in conventional RLSAs. A single-layered RLSA is much simpler in structure, but the slot length must be varied to synthesise uniform aperture illumination.

"Design Method, Analysis and Prototypes of Radial Line Slot Antennas" M. Sierra Castañer , M. Sierra Pérez', M. Vera Isasa , J.L. Fernández Jambrina Departamento de Tecnologías de las Comunicaciones. Universidad de Vigo. Abstract: The authors propose a design procedure and an analysis method for radial line slot antennas.

Influence of dielectric materials arrangement in multilayered ... In this study, linearly polaarised version of the antenna is considered. Thus, according to Davis et. al [9], linear polarisation is produced by spacing the slot pairs in a unit radiator a distance of λg/2 in the radial. Similarly, the slots in the unit radiator must be oriented with respect to the current flow line as appropriate. QUADERNI DELLA S I E V L Dual Circularly Polarized Radial ...

The experimental results for the first radial waveguide and a beam switching antenna application validate the proposed concept and model. Then, the same model is used to develop other reconfigurable radial waveguides or reconfigurable antennas which can found potential applications in communications and radars systems.
