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

The paper presents a circularly polarized radial line slot array (CP RLSA) antenna with a
nearly optimal monotonic variation of slot length with radius, in order to simultaneously …

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 …

Radial line slot antennas (RLSAs) are designed for high gain millimetre wave systems. Two
types of RLSA are tested in the 60 GHz band: one is the conventional structure consisting of …

Numerical slot design of a concentric array radial line slot antenna (CA-RLSA) with matching
slots is proposed for small aperture antennas. In contrast to the previous design for large …

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 …

This paper proposes the utilization of extreme beamsquint technique to minimize the
reflection coefficient of very small aperture radial line slot array (VSA-RLSA) antennas when …

A radial line slot antenna (RLSA) 400 mm in diameter is designed for a plasma source at 8.3
GHz as a candidate for a large area high density plasma source with a narrow process …

High gain and low noise characteristics are strongly required for DBS receiving antennas;
reflector antennas have been the most popular. Recently, various kinds of flat array …
