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 …

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 …

A radial line slot antenna (RLSA) is a circularly polarized high efficiency planar array. Two
types of RLSAs, a single-layered and a double-layered one, have been released …

A hybrid theoretical/experimental approach to the design of radial line slot array (RLSA)
antennas for receiving direct broadcast satellite (DBS) TV programs in Australia is …

A radial line slot antenna (RLSA) is a high-gain and high-efficiency planar antenna. A
linearly polarized RLSA (LP-RLSA) is attractive for applications of various subscriber radio …

In this communication, a simple and compact multiband circularly polarized (CP) slot
antenna loaded with metallic strips and a split-ring resonator (SRR) is proposed. The …

This article presents a circularly polarized corporate-fed radial-line slot antenna (CF-RLSA)
operating in Ka-band and realized in low-cost, low-profile printed circuit board (PCB) …

A design for linearly polarized radial line slot antenna (RLSA) is proposed. A novel slot
arrangement is presented which couples to the rotationally symmetric guided waves to …

Radial-line slot-array antennas (RLSAs) provide an extremely simple solution to achieve
high-gain circularly polarized radiation patterns without the need for complicated feeding …

This paper presents an effective full-wave procedure to optimize linearly polarized radial-
line slot-array antennas. The procedure is based on a recursive method for solving large …
