The basic structure of a RLSA consists of a set of slots placed on the upper face of a simple
parallel plate waveguide. Such guide is fed at its centre, typically by a coaxial probe. The …

Radial-Line Slot-Array Antennas (RLSA) have been a topic of research during the last
decade [1]-[3] due several attractive features they show. The RLSA configuration is basically …

The beam shaping of a linearly polarized radial‐line slot‐array (LP RLSA) antenna is
demonstrated with the production of a prototype with a broadened main beam pointed in an …

This paper presents a liearly-polarized radial line slot antenna (RLSA) with low sidelobes for
a radar mounted in the head of an aircraft. The RLSA is a circular planar antenna [1] so that …

A unified design of a single layer Radial Line Slot Array (RLSA) antenna of arbitrary
polarisation is presented. It addresses such tasks as the electromagnetic modelling of the …

High-gain low-profile antennas for microwave and millimeter-wave applications have been a
topic of exhaustive research during last decades. More specifically, radial-line slot array …

High gain linearly polarized radial line slot arrays (LP-RLSA) suffer from remarkable
degradation of the return loss. To overcome this drawback, this communication presents a …

Beam synthesis in linearly polarised radial line slot array (LPRLSA) antennas is
demonstrated with the production of a prototype with a broadened main beam pointed in an …

This paper proposes new topologies of linearly polarized radial-line slot-array antennas (LP-
RLSA) which uses slot-dipole pairs as radiating elements. Firstly, the basic design of the …

This article presents a new type of beam-tilted circularly polarized (CP) radial line slot array
(RLSA) antennas. When the conventional beam tilting method is applied to CP-RLSA …
