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. 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
