Abstract :
Four-arm Traveling-Wave (TW) antennas, such as the planar 4-arm spiral type, are considerably superior in performance to their 2-arm counterparts, but generally require a complex, bulky, and expensive feed. This paper presents a novel simple low-cost feed approach. The technique is applied to a GNSS (Global Navigation Satellite System) antenna to achieve good performance, low cost, and simple structure.
