Abstract :
This paper describes a new approach to the design of circularly polarised planar antennas. The power is injected at the centre of the array, and is distributed over the array by a straightforward feed network, using resonant linear arrays and notches etched on a few elements in order to produce orthogonal polarisations. Different configurations are selected and analysed with an antenna software based on the integral equations and validated on previous studies.<>
