Radial line slot array antenna

II. Radial Line Slot Antenna Structure Figure 1 shows the structure of the antenna. A Radial Line Slot Antenna is formed by a parallel plate structure, whose height is less than half a wavelength to avoid the propagation of upper modes. A radial TEM mode is generated through a coaxial probe (or several probes).

US6853344B2 - Radial line slot antenna - Google Patents This radial line slot antenna has many advantages, and is expected to play an important role as a millimeter wave band antenna for mobile communication, including radio LAN, in the near future. The name of the radial line slot antenna is often simply referred to as “RLSA”, which stands for Radial Line Slot Antenna. Influence of dielectric materials arrangement in multilayered ... Radial line slot array antenna (RLSA) is a planar slotted waveguide antenna which has low dielectric and conduction loss. Hence it can be designed with high gain and ... Radial Line Slot Antennas | SpringerLink 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, were released commercially for 12 GHz band direct broadcast satellite (DBS) reception.

A Reconfigurable Radial Line Slot Array (RLSA) Antenna for

An eight-ring radial helical array antenna based on a novel slot-coupled structure is designed and simulated. The novel coupling structure has the advantages of high power-handling capacity and excellent coupling ability. The simulation results of the array antenna agree well with theoretical calculations, and the aperture efficiency is about 78.1% when the beam is in the normal direction. US Patent for Radial line slot array antenna Patent ... A radial line slot array antenna in general has a plurality of slots arranged to fit a specific frequency (central frequency of used frequency band), and hence has a problem that the usable frequency band is narrow. The radial line slot array antenna described in Patent Literature 2 is intended to solve the aforementioned problem.

Omnidirectional antennas oriented vertically are widely used for nondirectional antennas on the surface of the Earth because they radiate equally in all horizontal directions, while the power radiated drops off with elevation angle so …
