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

Design of Monopulse Radial Line Slot Antennas Manuel ... Abstract: The authors propose the design of one radial line slot antenna with two simultaneous beams, one broadside beam and one conical beam. The antenna is a radial line slot antenna, with the slots placed on the upper plate in concentric rings. The radiation element is a slot pair, designed for getting left hand circular polarization. 23PM2B-04 Study of a High Gain Radial Line Slot Antenna in ...
