Radial Line Slot Antenna Design for Monopulse Space Debris ... The required gain is 40 dBi for this design, and the antenna is designed to maximize the gain at the central frequency. Both patterns are obtained with different excitations of the radial line slot antenna (RLSA). Basically, if the slots are placed in concentric rings, when the RLSA is excited in the centre, a conical or difference beam is ... Radial Line Slot Antennas | SpringerLink For the compact antenna design, a single-layered radial line slot antenna (RLSA) utilizes a radially outward traveling wave, and the slot length is varied to synthesize uniform aperture illumination. The DBS reception antenna consists of back plate, foam, slotted plate, and radome as shown in Fig. 1. The radial line is terminated by a matching ...

A Radial Line Slot Antenna (RLSA) was firstly proposed nearly 40 years ago [1] and became an important subject of studies as the perspective antenna for direct TV satellite broadcasting and any other wireless communications since 1980 [2]. Applications also include automotive collision avoidance radar, entrance radio link
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. Thus; termination with conical and frustum shaped elements are studied for a single layer radial line slot array antenna at 28 GHz in this paper. The sensitivity 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.

A Reconfigurable Radial Line Slot Array Antenna for WiMAX ...
A radial line slot antenna (RLSA) is a nonresonant multimode waveguide slotted array. To improve the power handing capacity, we design a radial line slow wave structure which replaces a traditional dielectric sheet. At the same time, the structure of the radiator unit is redesigned and optimised.
