PERFORMANCE STUDIES OF RADIAL LINE SLOT ARRAY (RLSA) ANTENNA ... PERFORMANCE STUDIES OF RADIAL LINE SLOT ARRAY (RLSA) ANTENNA AT 5.8 GHz ON DIFFERENT MATERIALS Omar Abdul Aziz Tharek Abdul Rahman 9.1 INTRODUCTION The type of dielectric material used as radial cavity in the Radial Line Slot Array (RLSA) antenna structure would influence the characteristics of the antenna, particularly its Radiation Pattern. Radial line s lo t array antenna at 28 GHz with modified ... Available online 23 May 2017 Coaxial to waveguide transition adaptor with disk shaped terminated feed probe was found to be an effective feed network for single layer radial line slot array antenna. However, further studies with the feed probe terminated in none disk shaped elements is required. Design of a slot-coupled radial line helical array antenna ... 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. BANDWIDTH ENHANCED AND SIDELOBES LEVEL REDUCED RADIAL LINE ...

A Reconfigurable Radial Line Slot Array Antenna for WiMAX Application 55 achieves a higher gain in comparison to the divisive broadside pattern. Figure 8 depicts the 3D simulation of the far field radiation patterns of the proposed antenna which is aligned with the measured radiation patterns as shown in figure 6 and figure 7. However, the Design of a slot-coupled radial line helical array antenna ... 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. Radial line slot array (RLSA) antenna design for point to ...
