Abstract
A broadband antenna designed to radiate high directive circularly polarized radiations is presented. This design utilizes spiral arms to achieve a broad frequency bandwidth and radiates circularly polarized fields. To enhance the directivity, the spiral arms are axially elevated to have a radiation beamwidth narrower than that radiated from an analogous spiral antenna in the upward direction. This antenna is suitable for many microwave applications. © 2008 Wiley Periodicals, Inc.
