In the design, high frequency laminate RT duroid 5880 and air gap were utilized with a modified dielectric coated 50 Ω SSMA connector as the coaxial to waveguide transition. The technique was experimented via Optimization of Radial Line Slot Array Antenna Feeder Design ... O. B.-Z. and M. Hakak, “A stable design of coaxial adaptor for Radial Line Slot Array Antenna.,” pp. 51–62, 2009. P. Davis, “A linear polarised radial line slot array antenna for direct broadcast satellite services.
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
slot antenna arrays is that a separate feeding structure/balun is required, typically composed of a radial stub and a transmis- sion line, which is potentially lossy.

the antenna aperture in this case. A radial line slot antenna (RLSA) for surface-wave-coupled plasma (SWP) is a promising candidate to this end. A novel slot arrangement in the aperture, consisting of densely arrayed transverse slots, was fabricated and tested. Radial Microstrip Slotline Feed Network for Circular
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 BANDWIDTH ENHANCED AND SIDELOBES LEVEL REDUCED … bandwidth and reduce the sidelobes level in linearly polarized Radial Line Slot Array Antenna at 28 GHz for 5G mobile communication system.
