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 …

In linearly polarized (LP) radial line slot arrays (RLSAs), reflection canceling slots (RCSs)
are used in addition to the radiating slots (RSs) to reduce the return loss. The densely …

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 …

A novel technique in simplifying the fabrication process of LP-RLSA antenna as well as
improving the reflection coefficient of LP-RLSA antenna is proposed in this paper. This …

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 …

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 …

Radial Line Slot Array (RLSA) antennas have appealing features including high gain and
high efficiency combined with a low profile. Especially by highlighting their structural …

The standard linearly polarized radial-line slot-array (RLSA) antenna exhibits poor return
loss as seen by its coaxial feed. This paper describes techniques that improve the poor …

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 …

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 …
