Abstract :
Spiral antennas generally offer advantages of circular polarisation, wide bandwidth and high efficiency, and may be configured to provide squinted beams through variation of the spiral parameters and adaptive arrays through multi-arm interleaving. In this paper, a new variation of the curved segment model is reported for the analysis of eccentric spiral geometries printed on grounded dielectric substrates
