Radial line slot array antenna

By author

Radial line slot array antenna (RLSA) is a low loss planar antenna which has ease of manufacture and possess attributes like high efficiency and gain [1]. It can be designed for linear [2] or circular [3], [4] polarization. It attracted attention in applications such as wireless LANs [5], local multiport

Radial line slot array (RLSA) antenna design for point to ... A new type of linearly polarized Radial Line Slot Array (RLSA) antenna developed by FR-4 substrate is proposed for outdoor WLAN point to point application. The WLAN is based on the IEEE 802.1 la standard and the operating frequency range is the upper UNII band (5.725-5.875) GHz. The frequency range is use for point to point microwave link. Radial Line Slots Array Antenna (RLSA) Performance based ... The radial-line slot array (RLSA) is prospective antenna for point to point communications due to its greater performances achieved as well as mass production opportunities by using of printed ...

DIAGNOSIS TECHNIQUES FOR PLANAR ANTENNAS USING ITERATIVE ... source reconstruction of a K-band radial line slot antenna (RLSA), and measured results are presented, compared with the designed data. Of course, this algorithm can be also be used for other kind of antennas as patch arrays. 1. Introduction One of the important parameters in antenna diagnosis is the field distribution on the antenna aperture.

Prototypes Development for Reflection Canceling Slot Design of Radial Line Slot Array (RLSA) Antenna for Direct Broadcast Satellite Reception.The extreme beamsquint technique to minimize the reflection coefficient of very small aperture radial line slot array antennas.

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. DESIGN OF RADIAL LINE SLOT ANTENNAS - core.ac.uk Concentric Array Radial Line Slot Antennas (CA-RLSAs) in which the slot pairs are split into several identical sectors. The Galerkin’s moment method is applied to solve the unknown excitation coeﬃcients of each slot. Thanks to the property of the symmetry of these slot pairs, so the numbers of the unknowns and the elements Prototypes development for reflection canceling slot Abstract: A radial line slot array (RLSA) antenna is a high gain and high efficiency planar antenna which is suitable for direct broadcast satellite (DBS) reception. The satellite communication market commonly uses the standard parabolic dish antenna. However, the use of this type of antenna …
